The BAR was designed (supposedly) for this pull the trigger and give a burst everytime your left foot hits the ground. I guess the M14 was the same thing but half the weight.
"In addition to shoulder-fired operation, BAR gunners were issued a belt with magazine pouches for the BAR and sidearm along with a "cup" to support the stock of the rifle when held at the hip. In theory, this allowed the soldier to lay suppressive fire while walking forward, keeping the enemy's head down, a practice known as "marching fire". The idea would resurface in the submachine gun and ultimately the assault rifle."
I can't imagine carrying that kind of weight around now, all day. 20 pounds OR 10 pounds. I'm too old and soft and fat. I guess I better pace myself when the zombies come until I get used to it.
What an exercise program. Get up in full battle rattle and patrol the neighborhood for an hour every day. Might upset some neighbors.
