Hmm, let's see I've seen several AT-4 rocket
launcher tubes(Got one for $100), a few M-72 LAW
Tubes, Complete Claymore setups both green/blue
a WWII bazooka,1 complete Dragon Anti-tank weapon
with stand and optics, various imported rocket launchers. 1 inert white phosphorous grenade.
and some others.
The by far most interesting was a Russian RPG-7
with 4 inert rockets complete with special backpack. Post anything that you've seen/own/ fired that made you're bug out.
