It has now been established that the Germans are using the Russian 76.2-mm field
gun, model 36, as an antitank weapon in Egypt.
It has also been reliably reported that there is a self-propelled mounting for the
weapon, although prisoners state that the first mount has not proved satisfactory.
German AP projectiles with Russian cases have been used, but in the case of HE, the
complete Russian round is used.
The muzzle velocity, with a 14.33-lb. shell, is estimated at 2,316 feet per
second. The estimated penetration of AP shot against homo plate is shown in
the following table:
||Penetration at 90° (in)||
||Penetration at 60° (in)|
Penetration at 90° may be slightly over-estimated.
Higher-velocity ammunition is provided in the AP-40 projectile, which
weighs 9.25 lbs. This is a converted HE projectile with a tungsten carbide
core weighing 902.5 grams (1.9 lbs). It has not been found possible to deduce
an exact muzzle velocity owing to the exceptionally high density of loading, and
the low temperature of the propellant. It is believed, however, that it is
probably between 2,800 and 3,000 feet per second. It may be has high as an
unconfirmed figure of 3,428 feet per second. The following figures give
estimated penetration for the 3,000-feet-per-second muzzle velocity, firing
against homo plate at a 60° angle.

The weapon itself is a field gun of split-trail design; it can also be
used for antiaircraft barrage fire. The vertical sliding breech block is
semi-automatic. Metal wheels with solid rubber tires are used.
Other characteristics of the gun are:
|Maximum range|| ||15,260 yds|
|Caliber||76.2 mm (3.00 in)|
|Length of barrel||50 calibers|
|Trunnion height||40.75 in |
|Elevation||-50° to +75°|
|Traverse||30° each way|
|Length of recoil (controlled)||38.19 to 21.65 in|
|Buffer liquid||5 quarts|
|Recuperator liquid||5.9 - 6.1 quarts|
|Compressed air||27 - 30 atmospheres |
|Shield thickness||.157 in|
|Weight of piece (with breech block)||990 lbs|
|Weight in action||1.78 tons|
The gun is equipped with rocking-bar reciprocating sights. The elevation
indicator is graduated in meters for the three types of projectile, and
in mils up to 800 (45°). The range indicator fitted to the gun examined was
German. Clinometers would presumably be necessary for antiaircraft barrage fire.
Ammunition is of the following three types:
AP 39; range 6,000 meters ( 6,540 yds)
AP 40; range 2,000 meters ( 2,180 yds)
HE; range 1,400 meters (15,260 yds)
