GERMAN armament captured by the
Allies reveals that the Nazis are now
using a kickless 75-mm. gun that can be
dropped by parachute and quickly brought
into position in support of advancing in-
fantry. In place of the heavy spring
mechanisms or hydraulic cylinders usually
employed to cushion recoil in guns of this
size, this new weapon has a |
butt consisting of an open tube
through which gases can es-
cape to neutralize the back-
ward push of the exploding
powder charge. Another novel
feature of the gun is that the
cartridge case of the shell it |
throws is made of paper in-
stead of metal. When the gun
is fired, this paper case is
driven out through the open |
butt—called a Venturi tube—in ~
the van of the escaping gases.
It is this simultaneous firing
of two projectiles in opposite |
directions that solves the prob.
lem of recoil.
Believed to have been inspired by a similar
Russian weapon, the Nazi gun weighs 225 1/2
pounds, is 45 inches high, and has a six-
caliber bore. It is capable of a 42-degree
elevation and a 20-degree depression. The
Russian recoilless gun, used for the first
time in the Russo-Finnish war of 1939, is a
40-mm. weapon weighing 425 pounds and
firing a projectile of about 2 1/2 pounds. It is
smaller than the German gun, standing only
20 inches high.
