"Most effective was to shoulder mount the tube like a Gustav or LAW, and snug the small baseplate into a tree trunk or sandbag. (You need something with a little bit of give or you run the likely risk of cracking the baseplate in half.) Then press the firing lever while using Kentucky Windage over the top of the muzzle. You had to be aware of arming distance."
Mind if I spread that to some (recent) users?
