i should have been more specific, i was referring to the soviet antitank weapon. role playing game is correct, but not what i was after. the term 'rocket propelled grenade' is one of those media-invented terms that they coin when they dont know what something is. seeing as this thing is a russian weapon, i would expect the correct term to be in the russian language, but the media term is probably pretty close. thanks for the answers, everybody.
It seems pretty clear then, Mark, that what you want is whatever the Russian for 'rocket propelled grenade' is! That's the answer that means an anti-tank weapon.
