Pictorial History
Weapons of the Military Police in the Cavalry
As of
January 26, 2012

This document is by no means to be considered
an authoritative reference work on military weaponry with accurate
nomenclatures, effective ranges, rates of fire or any such detailed
information. In some cases a little of this type of information is
provided when readily available for the viewers information. This
article is provided for the viewing pleasure of Military Policemen and
women who have served in the Cavalry Military Police and who enjoy a bit
of nostalgia and a look back at the history of the weaponry of the
Cavalry MP’s.
The Old Horse
Cavalry.

The prepared trooper sports his Model
1859 Sharps carbine, Model 1860 light saber, and a pair of 1851 Colt
Navy revolvers.
Notice the leather knot tied to the sword, wrapped
around the wrist to prevent dropping it, and the wide carbine belt
around the
shoulder, attached to the Sharps with a sling through its
o-ring.
A little historical note regarding the
photo above - there were several standard issue US Army Cavalry or
Dragoon pistols which will be covered later on in this document, but
many cavalrymen preferred the Navy revolver as it had a shorter barrel
and therefore fit tucked into the belt more comfortably. There is
historical proof that members of the 7th and 5th Cavalry even cut off 2
inches of their issue cavalry revolvers for this purpose.
Cavalry units and individual troopers
assigned as temporary provost units may have very well been armed as
shown in the photo above.
Model 1859 Sharps Carbine, 52
cal, single shot, breech loading originally issued during the Civil War
to Cavalry units

Standard issue Spencer Carbine which was
first used towards the end of the Civil War and was a large improvement
in that it had a seven round magazine which was loaded through the butt
plate of the rifle stock.
Many other carbines and rifles were
issued between the Civil War the Mexican War, but most were
unsatisfactory or not popular with the cavalry troopers. One that was
popular and was used by some cavalry units is shown below:

Model 1898 Krag Springfield .30-40 Rifle

Model
1860 Light Enlisted Cavalryman’s Saber
Note: There was a Heavy
version called “The Wrist Breaker” by the troopers that was not often in
use as it weighed 4 ½ pounds more than the light model

Remington 44 cal Cavalry Pistol
Just one of several versions of the
cavalry pistols issued to early Cavalry units

US Model 1873 Henry Nettleton Colt 45 cal Cavalry Pistol

M 1191 Colt
US Cavalry Pistol model 1873 .45 cal

Here is a photograph of an actual model 1873, M 1191 that is in the
possession of a hand gun collector and he claims that this pistol was on
the body of a dead 7th Cavalryman at the Little Big Horn and was stuffed
in the troopers boot. You will note the sawn off barrel. There were
supposedly several more like it at this battle site and they are in the
hands of other collectors. Some other collectors believe the Indians
sawed off the barrels and when re captured the cavalrymen kept them as
extra hide away guns – these boys went on patrol armed to the teeth.
M 1055 Old Dragoon pistol Model 1848
It varied from unit to unit, but
cavalrymen normally did not have a pistol holster on their belts as
there was no room what with the hook for the carbine on one side and the
saber on the other. In the old dragoon units they usually had saddle
holsters for their “Horse Pistols” and that tradition carried down to
some units. But as a rule the cavalrymen carried their pistols stuffed
into the front of their belts. Sometimes two or even more!

Here is a photograph of some troopers from
the 5th Cavalry and you will note the pistols tucked into their belts
Fort Bliss,
Texas
Prior to the formation of the 1st Cavalry
Division and during the Mexican War and the 1st World War, there were a
lot of changes in weapons within the US Army and these changes came to
Fort Bliss as well.

M 1903 Springfield bolt action rifle cal
.30 this was the rifle that SGT York made famous during WW I It was the
darling of the Drill Sergeants, Weapons Instructors, Drill team Captains
and Honor Guard Commanders as it was the perfect height and weight for
formal drill and ceremonies, looked good in a marching formation and was
accurate at long ranges.
The U.S. Model 1903 Springfield Rifle,
manufactured 1903 to 1945, this rifle replaced the Krag-Jorgensen and
was the primary U.S. battle rifle until 1936, when it was replace by the
M1 Garand. Some variation of the '03 rifle saw service all the way into
the early stages of the Vietnam War, were it was still utilized as a
sniper rifle in the form of the 1903A4.
Although authorized M-1 Garand rifles, the
original MP Platoon members had to draw M 1903 Springfield’s in 1942 as
the supply of these new weapons had not caught up with the demand yet
and the unit did not receive their M-1’s until just before they shipped
out from Australia for the Pacific Theatre.

US Army M 1911 .45 cal automatic pistol which was to become the main
side arm of the Army for years to come and later versions could be
converted to 9mm by changing the barrel and magazine – note the 45 round
on the left and the 9mm on the right. On March 29, 1911 this weapon was
selected as the official side arm of the US Army.
There are many versions of this weapon,
both civilian and military and all of them are excellent weapons. It is
one of the easiest weapons to dissemble and reassemble that the writer
of this document knows of and it will fire even after having lain on the
bed of a stream and in the mud over night covered in running muddy
water. Most MP’s that have qualified with this weapon did so at least by
firing Sharpshooter and many of them fired Expert. I don’t ever recall
seeing an MP with a Marksman’s Badge with a 45 pistol bar beneath it.
Easy to maintain, easy to shoot and easy to qualify with and talk about
knock down power!!!

US Army M 1917 Colt .45 cal revolver
There is a good deal of conflicting
history concerning this revolver both in the military and among gun
collectors. The writer of this document has sifted through a lot of this
written history and come to the following conclusion. This weapon was
originally intended for issue to officers only and then it was decided
that it should be a cavalry side arm but a good many of them ended up in
military police units. The primary reason for its manufacture was to
fill a gap in the availability of the M 1911 .45 cal automatic pistol,
then the standard US Army pistol. Colt and Remington were producing the
M 1911 at capacity, along with many other military arms, when the need
for more pistols for WW I became urgent. Production of the M 1911 could
not meet all requirements, so orders were placed with both Colt and
Smith and Wesson for a heavy frame revolver that would be compatible
with the .45 ACP cartridge used by the M 1911 automatic. By the time the
MP Platoon finally joined the 1st Cavalry Division in 1942, most of the
troops and regiments within the division had the M 1911 so the MP
Platoon got stuck with the 45 cal revolver hand me downs until they
arrived in Australia where they exchanged them for brand new M 1911’s.
Australia
Things now really
ratchet up for the MP Platoon, they receive jungle training, amphibious
landing training, new uniforms, new weapons and lots and lots of weapons
training – even on some weapons that the unit did not possess or were
authorized possession of in the TOE.
The MP Platoon finally
turned in their old bolt action Springfield’s and received brand New M-1
Garand’s. These were gas operated with an 8 round clip of .30 cal
ammunition and could be fired in semi automatic mode by just pulling the
trigger repeatedly. General George Patton once said “The single most
important weapon in WW II was the M-1 rifle” This was another weapon
like the M 1911 pistol in that it would take abuse and was easy to field
strip and clean. The only problem was not on the battle field, but on
the parade field (as many of you who ever received an M-1 thumb will
recall) and also like the .45 cal M 1911 this rifle had stopping power.

The MP Platoon also finally turned in their 45 cal revolvers in
exchange for brand new
M 1911 Semi Automatics in Australia.

This was the machine gun that was used for extended long range
sustained fire and was heavy as HE_ _!! This was not a weapon that two
men could lug around easily – especially in the jungle.
The Browning
M 1917 A1, water cooled .30 cal heavy machine gun.
The Ordnance Department adopted this
Browning water-cooled machinegun for use in the Army just after World
War I, superseding the M1917. The original World War I ammunition boxes
for this weapon were made of wood. The boxes were replaced by metal
during World War II.
Caliber: .30
Effective range (on tripod):
2500 yards
Maximum usable range: about 4000 yards

Maker: Browning
The MP Platoon received lots of training on
this weapon in Australia and as you will see later on, devised a way to
make it easy to transport. This weapon remained in use as late as the
Korean War.

M 1919 A-4 Browning Air Cooled light machine gun .30 cal.
The air-cooled 'A4 was much lighter and more
portable than its M 1917 A-1 water-cooled counterpart

rounds per minute
Effective range: 1000m (1100 yds)
The members of the MP Platoon got plenty
of training on this weapon as well. This weapon or variations of it
remained in use until it was replaced by the M–60 machine gun.

M-2 Air Cooled .50 cal heavy machine gun or more affectionately
referred to as
“Ma Duce!”
The Browning M2 .50 caliber (12.7mm)
Machine Gun, is a World War II era automatic, belt-fed, recoil operated,
air-cooled, crew-operated machine gun. The M2 is crew transportable with
limited amounts of ammunition over short distances. This gun has a back
plate with spade grips, trigger, and bolt latch release. The gun is
equipped with leaf-type rear sight, flash suppressor and a spare barrel
assembly. By repositioning some of the component parts, ammunition may
be fed from either the left or right side. A disintegrating metallic
link-belt is used to feed the ammunition into the weapon. The gun is
capable of single-shot (ground M2), as well as automatic fire.
This gun may be mounted on ground mounts and
most vehicles as an anti-personnel and anti-aircraft weapon. Associated
components are the M63 antiaircraft mount and the M3 tripod mount. The
M2 .50 Cal. flexible version is used as a ground gun on the M3 tripod
mount or various naval mounts. The M2 .50 Cal., M48 turret type, fixed
type, and soft mount are installed on mounts of several different types
of combat vehicles and ships. The weapon provides automatic weapon
suppressive fire for offensive and defensive purposes. This weapon can
be used effectively against personnel, light armored vehicles; low, slow
flying aircraft; and small boats.

Since this weapon had just been approved for
use by the US Army at the beginning of WW II, there weren’t many
available to the 1st Cavalry for training in Australia, but each man in
the MP Platoon did get to fire a few rounds for familiarization and
attend a class on the care and maintenance of this weapon. As anyone
knows who has ever fired this weapon it is easy to care for and so long
as you don’t loose the little head space gauge and the barrels are also
easy and quick to change (there is also a little trick for that as
well).
Pacific Theatre

M 1897 Trench Shotgun with Bayonet
These were originally developed for use in
the Philippines and used later on in WW I in the trenches and the Cav
MP’s loved them for use in guarding POW’s as well as clearing Japanese
hold outs from buildings and culverts in the Islands. It is this writers
understanding that although not on the TOE, the MP Platoon had dozens of
these and came by them easily, but the 20 gauge ammo was extremely
difficult to obtain. Years later the shot gun in many variations would
be a common item on the MP Company TOE’s. The writer of this document
clearly remembers a number of similar shot guns with a folding bayonet
in use in the Stockade at Fort Dix, New Jersey in the 1970’s.

Model 1923 Thompson Sub Machine Gun
Almost every NCO in the MP
Platoon had one of these and they were not on the TOE either.

Here is an MP Platoon MP directing traffic at the Division CP with
one of those Thompson’s

Here is a photo of a Water Cooled MG on a pedestal mount in a jeep. The
MP Platoon was authorized one of these machineguns, but not the pedestal
mount for it. They had two of these MG’s and a mount for both!

M-1 Carbine
Caliber: . 30 US Carbine (7.62x33 mm)
Action: Gas operated, rotating bolt
Overall length: 904
mm
Barrel length: 458 mm
Weight: 2.36 kg without
magazine
Magazine capacity: 15 or 30 rounds
The M1 carbine is an interesting little
weapon. The original request for a compact and lightweight shoulder arm
to replace service handguns for second-line (non-fighting) troops was
first issued by US Army in 1938. The idea behind this request was that a
shoulder arm, such as carbine, firing ammunition of moderate power, will
have more effective range and will be much simpler to train the users to
fire it accurately, than the standard .45 caliber semi-automatic pistols
or revolver. This request was probably the first recognition of the need
in the Personal Defense Weapon in the modern sense. Request was shelved
for some time and re-issued in 1940. It included the new cartridge of
.30 calibers but of power far less than of US general issue .30-06
ammunition. The cartridge, officially named the "cartridge, ball, .30
caliber, M1", was developed by the Winchester company. It was a
straight-case, rimless design with round-nose bullet weighting 110
grains (7.1 gram) and muzzle velocity of 1860 fps (~ 570 m/s). Muzzle
energy was about 2 times more than of .45ACP pistol cartridge but still
almost 3 times less than of .30-06 rifle cartridge. In the modern sense
the .30 carbine cartridge can be called an "intermediate" but the lack
of the muzzle energy and round nosed bullet limited the effective range
to about 200 meters or so. Anyway, it had still much longer range than
any pistol round of its time, along with moderate recoil. Many companies
submitted their designs for US Army trials but the winner eventually
became the Winchester. The design of the Winchester carbine is often
contributed to the David "Carbine" Williams, who were the developer of
the gas system.
Sometime during the Island operations, these
great little weapons showed up and were issued to most units within the
1st Cavalry Division in various quantities. The armor crewmen loved them
as they took up much less room in their vehicles than the M-1 or even
the Thompson Sub Machine Gun and the MP’s especially liked them as the
were easy to handle and control while searching POW’s and other
detainees.
TOE’s were finally brought up to date and the MP Platoon
was eventually authorized these great little weapons and they were used
extensively in not only the Pacific Theatre, but in Japan and Korea as
well.

M-3 A-1 Grease Gun
Although never authorized for the 545th MP
Company an occasional Grease Gun found its way into the organization.
They had a few of these in the MP Platoon during WW II and the writer of
this document saw one carried by a 545th MP in Song Be, Vietnam in 1969
Although not as famous as the Thompson Sub, this weapon had less moving
parts and was less subject to malfunctions due to lack of maintenance
and cleaning. It was also much less expensive and quicker to mass
produce. The only draw back was that it would “Cook Off” if fired in
long bursts for extended periods of time.
Operation: Fully Automatic, Blowback
Caliber: 45 cal (11.4mm)
Muzzle velocity: 280 mps (920 fps)
Ammunition: 45 cal ACP, 230 grain bullet, 5 grain charge
Capacity:
30-round detachable box magazine
Weight: 8 lbs.
Overall Length: 2
ft 5.8 inches, stock extended – 1 ft 10.8 inches, stock retracted
Rate of Fire: .50 – 450 rpm
Effective Range: 50 m (55 yds)
Japan
The MP Platoon, 1st Cavalry Division as
well as the rest of the Military Police Units world wide, finally
received the first standard issue Military Police Night Stick which was
Club, Police, M-1944. It took a while for them to be distributed to all
MP units in the Army and in many cases the MP units (such as the MP’s at
the Nuremburg Trials in Germany) had to make their own which was usually
done with Mop Handles. The Cav MP’s were no different and there were
many styles within the unit for a while as seen in the photo below.

Here are some members of the CG’s Security
Detachment at Camp Drake Japan with one of the many versions of the
improvised Night Sticks in use until issue of the standard M-1944 (It
looks like it was made from an old WW I entrenching tool handle?)

Here is a
photo of MP L.C. Shane (above) which was taken circa 1915 – 1919, unit
or location unknown. Note the revolver holster and the OG Sweater worn
in place of the Blouse or Jacket. The MP Arm Band may have been tan or
white or yellow but it’s difficult to tell with the old tin type photo.
He may have been in WW I in France? Or he might have been one of the old
provost troopers at Ft Bliss as we know for a fact that the MP’s at Ft
Bliss in those days were issued .45 cal revolvers. The “Billie Club” or
Night Stick also appears to be of the type hand made from mop handles
which was common prior to 1944 Photo complements of MSG Dick Burch.

The M-1944
was definitely in use by all members of the unit by the time it arrived
at Camp Crawford as seen worn by PFC Gould of the 545th MP Co in the
1950’s
In addition to this new issue Club, Police
M-1944, the MP Platoon and later the 545th MP Company continued to
maintain their proficiency on their individual and crew served weapons
in various field training exercises and trips to the weapons
qualification ranges. Their newest weapon aside from the Night Stick was
the M-1 Carbine which they used often during confinement operations at
the Camp Drake and later the Camp Crawford Stockades.
For those
history buffs among you that just have to have the documentation – here
is the US Army Specification No. 23-110, dated February 23, 1943 for the
CLUB – POLICEMAN, M-1944.

Browning Automatic Rifle .30 cal more
affectionately known as the BAR or BAR 30
M-1918 A-2
John Browning designed the BAR to
provide an automatic rifle for use during World War I. The M1918 saw
service toward the end of World War I. The M1918A2, adopted by the Army
in 1940, saw extensive service during World War II and Korea. The BAR
used .30-06 cal. cartridges in 20-round magazines. The BAR provided an
effective rate of fire of 550 rpm, and proved to be a very reliable
weapon during adverse operating conditions.
-
M1918 (1917) was selective to fire either
semi- or fully-automatic. The M1918 did not have the shoulder
support plate or bipod that was characteristic of later models. The
M1918 had a blade front sight and a leaf with aperture battle sight
with aperture rear sight.
-
M1918A1 (1937) was selective to
fire either semi- or fully-automatic. It had a shoulder support
plate hinged to the butt stock and a spike type bipod. The M1918A1
had a blade front sight and a leaf with aperture battle sight with
aperture rear sight.
-
M1918A2 (1940) was fully-automatic,
but selective at either Slow (300-450 rpm) or Fast (500-650 rpm)
rates of fire. The M1918A2 was originally issued with a spike based
removable stock rest which fitted in a hole in the butt stock. It
had a shorter hinged shoulder support plate and a skid type bipod.
Later modifications included a plastic butt stock and the addition
of a carrying handle. The M1918A2 had a blade front sight and a leaf
with aperture rear sight adjustable for windage.
As of the writing of this document it cannot
be determined if the 545th MP Co was ever authorized this weapon in the
TOE, but there is sufficient evidence to clearly indicate that some
individuals within the unit did in fact possess this weapon and used it
successfully in combat not only in Korea but also later in Vietnam. Many
of the older NCO’s in the unit really liked this weapon as it was much
lighter than either the water or air cooled MG’s in use at the time and
since the M-60 did not exist yet this was a perfect fire and maneuver
weapon. It also had a much greater effective range than either the M-3
Grease Gun or the Thompson Sub Machine Gun which were also very much in
use by members of the 545th MP Co. in Korea.

Photo of a BAR in use in Korea
The M-1 Garand was still very much in use
in Korea and of course the favorite side arm of all MP’s, the M 1911
A-1, .45 cal pistol as seen worn in a shoulder holster by CPT Mehl the
commander of the 545th MP Co during the Korean War below --

For a short while during the Korean War
several members of the 545th MP Co had M-3 Grease Guns until one evening
one of them “Cooked Off” Discharging its entire magazine before ceasing
fire. The next day all the Grease Guns were replaced with M-1 Carbines
and never seen again in the 545th in Korea or Japan.
Vietnam

M 67 Recoilless Rifle
The M67 90mm recoilless rifle is a
lightweight, portable, crew-served weapon intended primarily as an
antitank weapon. It can be employed in an antipersonnel role too. It is
designed to be fired primarily from the ground using the bipod and
monopod, but it may be fired from the shoulder. It is an air-cooled,
breech-loaded, single-shot rifle that fires fixed ammunition. The rifle
is equipped with a manually operated breech mechanism and a
percussion-type firing mechanism. It is designed for direct firing only,
and sighting equipment for this purpose is furnished with each weapon.
Although the 545th was officially authorized
four of these weapons, CPT Lawhead and his boys had to dig up some
Fleshette rounds before they could use one successfully during the early
1960’s in Vietnam. They especially liked the results the Fleshette
anti-personnel round provided! “Charlie” was not fond of this weapon!
This was a time of new concepts, new weapons,
new aircraft, new uniforms, new equipment and new thinking in the US
Army. When the 11th Air Assault became the 1st Cavalry Division at Fort
Benning, Georgia, they (and that included the 545th MP Company) had
already undergone Air Assault training and training on many new weapons
which they were issued and took to Vietnam with them. Now the 545th were
not only Cavalry MP’s they were Air Mobile Cavalry MP’s as well! The
545th MP Co arrived in Vietnam in the old style fatigue uniform, but
with an entire inventory of new weapons.



M-16A-1, A-2 and with the M 203 grenade launcher attached.
A lightweight, air-cooled, gas-operated,
magazine-fed rifle designed for either automatic or semi-automatic fire
through use of a selector lever. There are four variants - the
M-16A1/A2/A3/A4. The M-16A2 incorporates improvements in iron sight,
pistol grip, stock and overall combat effectiveness.
Accuracy is enhanced by incorporating an
improved muzzle compensator, three-round burst control, and a heavier
barrel; and by using the heavier NATO-standard ammunition, which is also
fired by the squad automatic weapon. The M-16A3 is identical to the
M-16A2 but has a removable carrying handle that is mounted on a
Picatinny Rail (for better mounting of optics) and is without burst
control. The M-16A4 is identical to the M-16A2 except for the removable
carrying handle and Picatinny Rail. Placed into service in 1964.

M-79 Grenade Launcher
“THE BLOOPER or THUMPER”
This weapon first appeared during the
Vietnam War and closely resembled a large bore, single barrel, sawn-off
shotgun. The first M79 Grenade launchers were delivered to the US Army
in 1961.
The M79 was designed as a close support
weapon for the infantry, and was intended to bridge the gap between the
maximum throwing distance of a hand grenade, and the lowest range of
supporting mortar fire, an area of between 50 and 300 meters.
The
M79 was a single shot, shoulder fired, break-barrel loading weapon which
fired a spherical 40mm diameter grenade. The M-406 40mm HE grenades
fired from the M79 traveled at a muzzle velocity of 75 meters per
second, and contained enough explosive within a steel casing that upon
impact with the target would produce over 300 fragments at 1,524 meters
per second within a lethal radius of up to 5 meters (?). Stabilized in
flight by the spin imparted on it by the rifled barrel the grenade
rotated at 3,700rpm, this in turn after 15 meters (?) of flight armed
the grenade.
For close range fighting the Army came
up with two types of M79 rounds. The first was a Fleshette round which
housed approx 45 small darts in a plastic casing, these rounds were
issued on an experimental basis. Later this round was replaced by the
M-576 buckshot round. This round contained twenty-seven 00 buckshot
which on firing was carried down the barrel in a 40mm plastic sabot,
which slowed down in flight so the pellets could travel in their forward
direction un-aided. The M79 could also fire smoke grenades, CS gas, WP
and flares.
The M79 had a large flip up sight situated
half way down the barrel, with a basic leaf foresight fixed at the end
of the barrel. The rear sight was calibrated up to 375 meters in 25
meter intervals. In the hands of a good experienced Grenadier the M79
was highly accurate up to 200 meters. Later in the war the M79 was
superseded by the M203 40mm launcher which was fixed beneath the fore
grip of the M16 rifle.

M-60 7.62 mm
Machine Gun
The M60 Machine Gun was type classified
in 1957 by the U.S. Army. It fires the standard NATO 7.62 mm round and
is used as a general support crew-served weapon. It has a removable
barrel which can be easily changed to prevent overheating. The weapon
has an integral, folding bipod and can also be mounted on a folding
tripod.
Length: 42.4 inches (107.70
centimeters)
Weight: 18.75 pounds (8.51 kilograms)
Bore
diameter: 7.62mm (.308 inches)
Maximum effective range:
3609.1 feet (1100 meters)
Maximum range: 2.3 miles (3725

Rates of fire:
Cyclic: 550 rounds per minute
Rapid:
100 rounds per minute*
Sustained: 100 rounds per minute*
(*
with barrel changes at each 100 rounds)
Unit Replacement Cost:

The M60E3 7.62mm machine gun is a
lightweight, air-cooled, disintegrating metallic link-belt fed, portable
or tripod mounted machine gun designed for ground operations like its
predecessor, the M60. It is gas operated with fixed headspace and timing
which permits rapid changing of barrels. (Associated components: Mount
tripod, machine gun, 7.62mm, M122). Slightly different from its
"parent," the M60, the M60E3 has a receiver-attached bipod which easily
deploys for stability. It has an ambidextrous safety, universal sling
attachments, a carrying handle on the barrel, and a simplified gas
system that does not require safety wire to prevent loosening. However,
the light weight barrel is not safe for overhead fire and is not capable
of sustaining a rapid rate of fire of 200 rounds per minute without
catastrophic failure of the barrel.
The M60E3 (light weight version of the parent
M60) was fielded with the intention to reduce the load carried by the
gunner. However, the reduction in weight resulted in firing limitations
and a loss of reliability that severely restricts the use of the weapon
in the Fleet Marine Force. Consequently, troop acceptance of the E3 has
been very poor. This gun will be replaced by the M240G.
AMMUNITION
The preferred combat
ammunition mix for the M60 is a four-ball (M80) and one-tracer (M62)
mix. Again, the four-and-one mix allows the gunner to use the TOT method
of adjusting fire to achieve target kill.
Note: Each squad was
authorized two M-60’s in the TOE, but the 545th ended up with quite a
few more than authorized and used every one of them often.
The 545th
continued to utilize the M1911A1 as a side arm and of course the Ma Duce
continued as the Heavy MG. As indicated earlier in this document, the
combat pump shot gun was by now a mainstay in the MP Company and the
545th had several models – all pumps and mostly Remington’s
Historical note: The 545th also were issued Flack Vests and Jungle
fatigues shortly after arrival in country.

Desert Storm
The 545th MP Company arrived in the Middle
East with Vietnam era weapons as seen in the photo below of 2nd Lt.

Jungle Boots. They were still authorized M60’s and the M2 .50 cal MG’s
The US Army had begun to issue the M9 9 mm pistol and some replacements
arrived with them, but since there was no ammunition within the division
for them, the Provost Marshal, LTC Anthony Lupo had them turned in and
replaced with the .45 cal M1911 A1.

double-action pistol placed into service in 1990. The M9 is the primary

The Iraq War
The 545th MP Co was now authorized
the M9 9 mm pistol first issued in Desert Storm and continued to use the
old reliable weapons from WW II such as the Ma Duce. They had their
SAW’s and their M-4’s and there were some improvements in Body Armor as
well. They also finally received a new weapon which had been in use in
Desert Storm but had not been issued to the 545th at that time, the MK
19. An entire new generation of CBR gear was also now in use at this
time.

I hope you have all enjoyed this little walk
back in time through the weapons history of the Cavalry Military
policemen. I did not cover the mines, disposable weapons (LAW), grenades
or pyrotechnics that were often in use by the 545th MP Co as they were
numerous and varied by platoon, geographical area, dates and operational
requirements. Comments, suggestions, additions or corrections may be
