Interesting Unusual Guns

[alanint]

If it's the scene where two British troops load the weapon with a large, mortar style round and are firing at the German tanks coming over the bridge, it was a PIAT. The technical term is a "Spigot Mortar"

BTW, the PIAT is the only "Bazooka" style weapon from WW2 you can own without any ATF approval or other permits.
