Fired all the machine-guns in the Army up to the M2 .50 Cal. Laws, and AT-4 Anti-tank rockets. 25mm on the Bradley. Also got to drop a few 4.2 mortar rounds.
Longest shot was with the TOW guided missile at a target over 3000 meters.
Biggest shoulder fired was the M47 Dragon. I was a new Private in Germany and they handed my the Dragon, not the training round, but with the HE warhead and blew a huge hole in the side of an armored personnel carrier target at 1000 meters.
