superc123456: I know under normal circumstances you can't, my game glitched.... I started T.White (super trooper) out with a Garand and upgraded him with a rifle grenade, somehow he kept it when i upgraded him with a BAR and normal grenade... this has never happened to any of my units before or since, but I guess since my guy was a super trooper, he modified his weapon, I know you probably don't believe me but I regretfully admit I did not get a screenshot it...
T. White:RIP... Last man standing for about 15 waves because of constant arty strikes cutting off reinforcements. Took out 3 panzers along with countless Germans armed with only Bar machine gun, grenade and rifle grenade.... While all hell broke lose, he stood and fought upon his rock, only to be brought down by a firebomb
