I found myself a Humvee with a 40 mm grenade launcher - yay! But when I fire the launcher the grenade explodes right on the Humvee. So I take it off and use it by hand - and the grenade explodes on me, as though I had targeted myself. This happens completely consistently. I am properly selecting targets far away. Distance of the target doesn’t seem to matter. Is there some extra step I need to do to use a grenade launcher? I am using generic guns, if that would somehow affect things (all other guns I’ve found work fine).
