BEANO T-13 - small baseball shaped grenade used for large throws do the size cut back back on explosive power making more useful has a concussion force grenade.
Who, Me? - Developed by a WW2 US scientist to be used by French resistance fighters against the NAZIs. Do it didn’t finish development till after the war it was designed has military grade stink bomb. I belief the effects from this could cause blurred vision and players could see enemies effected by with 10 meters of each other on the map do the effect of be seen on ingame map gos away after 10 secs. Also because of it’s wide area of effect it can also effect Allie’s even in blast area.
Explosive water canteen - Used US Army intelligence during WW2 and abit after Carry’s only 1/3has much has a normal ingame flask but works has a second grenade the player can throw.
Type 99 AT Grenade-WW2 JAPANESES weapon communly mistaken has a mine even do it’s meant to be thrown like a Frisbee to glide and land/slide on impact on top of or under a tank.
