Luckily there are still two WWII veterans that I have talked to about the extent and duration of their firearms training.
The first is the Pot Shots Chairman for my Gun Club. Sammy volunteered and was accepted into the Navy. He was a communications specialist; his job was to relay the communications between the Command Ship and the Ground Commanders. That meant he was landed second wave on Iwo Jima and Okinawa. If you don’t know, to be on an early wave was tantamount to a death sentence.
Sammy got exactly twenty shots of familiarization before he shipped to a combat zone. Ten shots at 200 yards one day, ten shots at 200 yards another day. Each time at the range he was issued a different carbine. One of these carbines, with the L left on the highest elevation, aiming at the top of the target, he was able to hit the middle!
Sammy teaches Pot Shots because he is certain that if his Dad had not taught him how to shoot he would be dead now. Sammy does not like to talk about it, still has nightmares. He has referred to the soldiers of that era as “cannon fodder”.
The second is my Uncle. Still alive and was 101 Airborne. Dropped Normandy, Market Garden, captured Bastogne.
He had exactly nine rounds of familiarization with his M1919 before he dropped over Normandy. He, and his assistant gunner, were so unfamiliar with the mechanism that they did not know it was unsafe to have a round chambered: he assumed there was some sort of a safety. As they were setting up the M1919, his bud had his finger over the muzzle. They managed to bump the trigger mechanism on the ground and his Bud lost that finger.
Prior to the war he lived on a farm and ran a Trap Line and hunted small game for food. The family were so broke that he only wore shoes in the winter. I am certain that his early exposure to firearms helped him shoot straight.
Their experiences are consistent with what I have read in print, the US military was just shoveling people out to the front. If you had not learned marksmanship before you got out there, you had to learn on the job. Life expectancy for a front line Dogface was in weeks, not months. So, you were probably dead before you got a good weapons zero. The American Rifleman ran a series during the war about marksmanship and the services. I forget the author. By the time you get to 1944 Officers were forbidding their men to shoot at targets 300 yards or greater. The hit probability was zero and it just got the enemy mad.
And guess what, this low standard of marksmanship is with us all the way up to our invasion of Iraq. Private Jessica Lynch had so little weapons training that she did not know how to clear a jam in her M16. She said on 60 minutes “it jammed”.
