My grandfather loved talking about his techniques for firing his BAR in WW2. He took immense pride in devising his own style for this enormous gun, given that he was such a tiny guy, especially back in 1944. He weighed only 116 lbs. at the time, and the Browning Automatic Rifle weighed approximately 15 lbs. and he also had to lug 20 lbs. of ammunition.
In this deleted scene from the documentary, he shares his unique approach to firing just a single round from the BAR.
