So, this is a very minor detail and very nitpicky of me, but if we were aiming for “historical accuracy” then soldiers should aim their pistol with only one hand.
Currently, this is how soldiers look when aiming a pistol
This appears to be based off of the Weaver Position, a shooting position developed by Los Angeles County Deputy Sheriff Jack Weaver during freestyle pistol competition in Southern California during the late 1950s, and not popularized until there after.
During the Second World War soldiers and police were not trained to shoot from the two handed position. Instead, there were two predominant one-handed shooting positions generally taught; the bullseye position and the point-shooting position.
In the Bullseye stance, the shooter stands erect, with a firm grip and straightened arm in order to aim. This is generally more something used for shooting at moderate distances, as close-range mobility may be poor.
The second position is the point-shooting position, where the shooter stands in a crouched or semi-crouched position, typically not aiming directly down the sights until ready to fire. This position is better for shooting on-the move, and would be ideal for Enlisted.
Finally, here is an old training video demonstrating the point-shooting technique.
