The M1 with grenade thrower fires an anti-tank rifle grenade, but the grenade in-game does nothing to armor so it clearly is a frag grenade instead. But there should be a different model for a frag grenade as it looked different in real life.
Either the model should be changed to the frag type, or the attributes of the current one should be updated to be anti-tank/anti-armor.
WW2 era training video, timestamped for rifle grenades
Same thing for german Schiessbacher grenade launcher. Ingame model has the middle type of projectile, which is supposed to be anti-tank type.
m9a1 was indeed a anti tank grenade. even the m11a3 (if i remember correcly) variant was a practice grenade (dummy) both share the same design we see ingame.
the anti personel grenade was more like a exposed “pineapple!” mk2 grenade on a base tube
Yeah the “pineapple” type grenades are explored in the video after the AT-variant, both a timed variant and one that explodes on impact- interesting content.
