Crew =4, am I going senile or what? I was in the A/T platoon for a couple of years and it seems to me that we had 5 men in the gun crew not includiding the tow vhicle operator.

The gun commander
No, 1- the layer
No. 2-the loader
No. 3-the man who handed the rounds to the loader
No. 4-the man who brought the rounds from the carrier

More info would certainly be interesting.
