It happens that you thought you were cleared to shoot but something was apparently in the way and your rpg explodes in your face.
Please consider adding a safety distance also to rocket launchers as they
have in real life/similar to underbarrel grenade launchers. The rocket must travel for example 10 meters at least before
activating.
Trying to shoot rocket for example from the rocks on crossing is just suicide because the collision is not aligned with meshes.
