Grenades seem simple enough to use. Flip off the safety clip, pull the pin, throw the grenade. And yet, people manage to screw it up pretty badly all the time. And I’ll just say this, the grenade test on Expert Infantry Badge testing is always one of the most difficult to pass. But hey, that’s what training is for.
That nice boom is one of the things that makes live fire grenade training one of the funner ranges to run.
