I get kitted up in a WWII uniform, gear, boots and helmet. In my case, US Paratrooper gear (watch Band of Brothers, Saving Private Ryan). We do displays and have training events. Occasionally we have a dedicated tactical, when the Allies (Brits, Aussies, Poles and Russkies) face off against German reenactors (mostly SS) for a full scale battle. Rifles firing blanks, grenades going off and rain.... dammed cool experience.
