Infantry really needs a few more anti tank weapons. I'm thinking RKG-3 for warsaw pact supplied army's and a rifle fired grenade like the energa for western supplied.
It is not the antitank weapons, it's a "last chance" weapon. Even during WWII AT grenades there more to calm the infantry. In the 80s it's effectiveness around zero.
Currently you waste the guy with the RPG and then go around running over the rest of the squad. Seems silly.
Around the state is no more expected. Effective AT weapoons are: SPG-9, BO-10/BO-11, M40, Milan and other ATGMs, not a grenades.
