Hawkeye_Joe Posted August 7, 2009 Report Share Posted August 7, 2009 http://www.lonesentry.com/features/pics/tank-gunnery-subcaliber-800.jpg http://www.lonesentry.com/features/pics/tank-submachine-gun-800.jpg Subcaliber firing was used by the U.S. Army to develop a tank gunner's accuracy, speed, and confidence without the costs and disturbance of firing the main armament. In general, the coaxial machine gun was used for the subcaliber training. However for fire adjustment training, a standard submachine gun was mounted outside the tank. Until a standard mount could be developed, the Tank Gunnery manual recommended the following mount for the 75-mm gun on the M4. For firing, the submachine gun was connected to the firing solenoid from the coaxial machine gun. Source: Tank Gunnery, War Department Field Manual FM 17-12, July 10, 1944.

Norm Posted August 8, 2009 Report Share Posted August 8, 2009 Well...it looks like it would have been a good way to keep the Nips and Jerrys off the turret! Link to comment Share on other sites More sharing options...
GUNGUY45 Posted August 8, 2009 Report Share Posted August 8, 2009 Outstanding photos, We used a similar system on our M60a1/a3's for sub cal training, but it used an M16a1 with a .22 sub cal device. (how about that, a sub, sub cal) Pete Link to comment Share on other sites More sharing options...
