My oldest brother trained on the recoilless rifle (jeep mounted) in the mid 1960s with the Canadian Army. I've seen them in museums and was amazed at how long they are. I don't envy the soldier in that film using a shoulder fired version.
They haven't got any lighter over the years ether. 100LBs of the lightest kit the army has every fielded is still 100Lb. lol
These posts of old Army films (and stuff) are great.What was the inspiration to get you to go searching?
I have an interest in post world war 2 and pre-Vietnam Era conflicts, and would some day. If I ever get the money that is make a Korean War range of figs in 28mm
