I was younger then mind, but I carried it on one shoulder and we had a heavy leather glove and liner for the left hand. that was so we could always lay hands on the jacket without a fear of being burned for a second at least. Even if just a bit hot, we could get it up on the shoulder with the pistol grip in the right hand and carry on... There was only the two of us, no number 3. We'd trade back and forth carrying mind. I was actually the number 2. I was bigger so I guess they figured I could be the mule...It wasn't that bad. Ammo on the other hand, I couldn't see how a man could carry more than three belts of 220 wrapped around him like snakes. It was not possible for me...660 was it. That was heavy.
