M1918A1 Browning Automatic Rifle (BAR) was created in 1917 by
engineer John Browning. This new weapon was to replace the French
Chauchat light machine gun still used at that time in the U.S.
First used by American troops at the end of World War I, the M1918A1
model was also used during the Second World War.
In 1940, a new BAR model was created, called M1918A2, offering
two different shooting modes, a slow one (300-450 rounds per minute)
and a one fast (500-650 rounds per minute). It is also fitted
with a fire shooting cover removing flames and allowing the shooter
to hide its position during night fights.
Also used during the Korean War, the BAR has enabled platoons
of U.S. forces to have a major fire power. But its main shortcoming
is that its charger contained only 20 bullets. The BAR magazine
was so to avoid any overheating of the weapon. The BAR magazine
is empty in less than 4 seconds during a continued fire.
