Although not as iconic as “potato masher” this german hand grenade was used quite extensivelly.
It’s production was actually greater (if I remember correctly) than stielhandgranate.
It would be nice to add this to the game. Probably only as a skin though.
Theoretically it could have a second “firemode” to use it as a mine but then we would have to find a counterpart for allies and deal with all other problems (like 3 grenade-mines per soldier thanks to awesome grenade pouch).
