Machine Guns
Lewis Gun
| Obsolete before the War even began, the Lewis Gun dates
back to before World War I. Designed by US Army Colonel Isaac Newton
Lewis, the gun was never officially adopted by the Americans but was
quickly accepted by the British who used it extensively during World
War I. The most striking feature of the Lewis Gun is the cooling jacket
that wraps around and extends beyond the actual barrel of the gun.
While it was relatively heavy for one man to carry it was rugged,
reliable, and accurate. It was often found mounted on vehicles during
the first few years of the war and continued to be used as an anti-aircraft
machine gun in the Royal Navy and with Home Guard units through
out the war.
According to more than one source, The Lewis Gun was used by the
LRDG, because it was more suited for their mission. It is never
fully explained how but the assumption would be the higher rate
of fire and the capacity of the pan magazines. |

Vickers GO (Vickers Gas Operated) --
The 'K' Gun
| The Vickers Gas Operated or VGO (often referred to
as Vickers K) is probably the machine gun most associated with the
SAS because this small aircraft pattern machine gun was mounted on
their jeeps
The VGO has a somewhat long and winding history. The VGO is a
modified version of the Vickers Berthier or VB. While similar to
the Bren gun in appearance and some aspects of function, the origins
of the VB lay elsewhere. The VB was a license built copy of the
French Berthier LMG. The French Berthier LMG was originally designed
by General Adolphe V.P.M. Berthier. Its design predates World War
I.
The Vickers Company of Great Britain obtained a license to build
a copy of the Berthier machine gun in 1925. In 1927 Vickers submitted
their version of the Berthier for machine gun trials. The light
machine guns was officially designated Mk1 Light Machine Gun by
Vickers but was commonly called the Vickers Berthier or VB.
The VB was Vickers entry in the early machine gun competition to
replace the Lewis Gun. The VB functions in almost every respect
the same way that the Bren does but failed to find followers in
the British Army. The VB was adopted by the Indian Army as their
standard LMG before the British adopted the Bren and continued to
be manufactured in India throughout the War. There was one crucial
difference between the Bren and VB. Due to the design of the breech
block on the VB it's rate of fire could be adjusted to as much as
1,200 rounds per minute. It was quickly realized that a MG firing
at such a rate would be ideal for anti-aircraft use and so the VB
was modified for use in Aircrafts. When the VB was adopted as an
observer's gun in aircraft it was known as he VGO.
The weapon was adopted because there were many of them not being
used by the RAF in the ME. There was subsequently a tussle with
them because the Ground Defence Officer decided they would be good
for airfield defence
It is said that David Stirling settle on the VGO to arm his jeeps
because it was a anti-aircraft gun and what better weapon to use
on aircraft than an anit-aircraft gun. With the outbreak of the
War it was quickly realized that aircraft speed had progressed so
much that it was virtually impossible for an observer in a moving
aircraft to engage another aircraft with the free swinging LMG.
Fortunately for Stirling's SAS and members of the LRDG, the VGO
was quite effective as a jeep or truck mounted machine gun against
stationary targets and even against strafing aircraft.
So why do so many people call the VGO, the Vickers K? That's simple.
It is what Vickers, the company that produced the gun, called it
commercially.

Vickers Machine Gun (Sometimes called
the Vickers Maxim)
| The Vickers Machine Gun was virtually
a lightened Maxim Gun built under license by Britain and throughout
the Commonwealth.
It was the standard medium/heavy machine gun of the British army
from before World War I and up to 1960. While most armies had adopted
some kind of air cooled machine gun for their principle MG, the
British continued to rely on the water cooled Vickers. Despite its
weight it was unsurpassed in reliability. As long as the condenser
was kept filled with water, the Vickers could be fired for an indefinite
period of time.
What's more, the British soldiers held the Vickers in absolute
awe, considering it better than any other MG ever made. With such
un-dying devotion the Vickers was never considered obsolete and
the British never thought twice of of developing a new machine gun
to take its place. |

Browning AN M2 .30 Machine Gun (.303 Mk II in British Servioce)
(Also called: Browning Air Pattern or Vickers
Armstrong)

Developed by Browning after World War I and adopted by
the United States Army in 1929, the AN M2 .30 caliber machine
gun was an excellent weapon for its time. Initially chambered
to fire the standard U. S. .30 '06 Cartridge (the thirty,
aught six) when the machine gun was adopted by the Royal Air
Force it was manufactured by Vickers Armstrong to fire the
.303 rimmed cartridge (the Brutish Standard) and its nomenclature
changed to Mk II **.
The machine gun was designed to fire hydraulically as a wing
mounted gun but was also adopted as hand fired mount for use
in bombers and reconnaissance aircraft. It was considered
rugged, reliable, and accurate. It was only capable of full
automatic fire.
One source claims the first Mk II to be used by the LRDG
were salvaged from a shot down Hawker Hurricane. If this was
the case, the machine gun would have been modified with the
addition of pistol grips or a metal tube that was welded to
a small metal plate, which acted as butt-stock and trigger
at the same time. |
Specifications for MK II:
- Caliber: .303 Rimmed*
- Action: Recoil
- Weight: 23 pounds
- Length: 39.8 inches
- barrel: 23.9 inches
- Rate of fire: 1140 RPM
- Muzzle Velocity: 2840 FPS.
* for models made for British service. |

Browning AN M2 .50 Machine Gun
(Also called: Browning .50 Air Pattern, M2
Air Pattern.)

Developed as a replacement for the AN M2 .30 MG, the .50
caliber is virtually an identical copy only larger. Unlike
the .30 version this model was not chambered for a specific
British caliber but instead the British adopted the American
50 caliber round.
The machine gun became the standard wing armament for most
U.S. fighter planes and was also used in American bombers
for their numerous gun stations. Like its smaller brother,
the weapon proved to be tough, reliable, and accurate. Again,
some models were subcontracted and made by Vickers Armstrong.
This is not the same gun as a Vickers 50, however. Unlike
the smaller .303 version, the 50 seemed to only have spade
grips added an not the metal butt-stock made from tubing.
The main differences between the AN M2 .50 and its cousin
the M2 HB (heavy barrel) are:
- Faster rate of fire (the AN M2 is almost 300 RPM's faster)
- It weighs 17 pounds less
- Can only fire automatic (the M2 HB can fire single shots)
- no quick change barrel
This is not the same as the Vickers .50 but some sources
seem to confuse the two machine guns. |
Specifications:
- Caliber: .50 (U.S.)
- Action: recoil
- Weight: 61 pounds
- Length: 64 inches
- Barrel: 37 inches
- Rate of fire: 750-800
- Muzzle Velocity: 2900 FPS

Mk V Vickers .5 Inch Machine Gun
(Vickers 50)

(Mk. III Naval .5 Vickers)
First entering service in 1932, the Vickers
.50 caliber machine gun was designed primarily as an anti-aircraft
weapon and was used extensively in this role.
The Mk III (shown above) was the Royal Navy version. The
Mk V (the final improved version) approved in 1935 and used
in armored fighting vehicles. About 1,000 were made. The most
noticeable difference between the .303 Vickers and the .5
is the overall size, the larger flash hider on the end of
the barrel, and the fluted water jacket. and the pistol grip.
(All. .5 vickers have the fluted jacket while only some .303
Vickers have them.)
The Vickers used a shorter, less powerful round than the
Browning M2 series and the rounds were not interchangeable.
Vickers .5 MGs were primarily mounted in early British AFV,
especially the light tanks. It was also mounted in Bren Bun
carriers. Unlike its smaller cousin, the .5 in. used a pistol
grip intead of the dual spade grips. The pitol grip was located
under the gun's receiver. Pictures of the AFV .5 in. Vickers
can be found in Brendan O'Carroll's book, Barce Raid.

Browning M2HB
The least used heavy machinegun in the LRDG was the Browning M2HB.
The HB stands for Heavy Barrel. Originally designed near the end
of WWI the Browning .50 was basically an enlarged version of his
.30 M1917 mg. Originally the gun water cooled and designated M1921.
By 1936 the designation was changed to M2. Two variants were made
for the gun around that time. The AN-M2, described above was the
first air-cooled version which was acceptable when used in aircraft
because the moving air and lower temperatures kept the barrels from
over heating. Unfortunately this was not the case with the ground
mounted versions. When fired from a ground mount, the AN-M2 had
a tendency to overheat and if prolonged fired continued, the barrel
could melt and warp. The solution was to make a heavier barrel that
could be changed more easily that the barrel of the AN-M2. This
became the M2HB.
While the Vickers .5in Mk. V and the ANM2 were the most commonly
used fifty caliber machine guns used by the LRDG, by 1943 some M2HBs
were making there way onto the trucks. A possible advantage of the
M2HB was its slower rate of fire (compared to the AN-M2) allowing
it to conserve ammunition. One unique aspect of the M2HB is its
ability to fire single shots. No other heavy machine gun used by
the Western Allies had this ability.
