You know, the staff input of "point of perspective" seems inconsistient. It speaks of grenades, but it happens usually before any promotions, so it makes me ask where the hell such a guy got a grenade.
I get its an attempt to mix lore with helpful tips, but it really doesn't make any sense. Besides, quartermaster wouldn't really be involved in interrogations would he?
I might propose an alternative however
"Hey commander, we had a.. ...small issue in the storage area. One of the men decided he would try to be slick, try throwing his gear into the designated storage shelves, but it ended up hitting a fire suppression sprinkler nozzle in the ceiling, breaking it open and drenching the storage area. Nothing important was damaged but I gave him a good ass chewing for not relying on forklifts for putting things on the right shelf, nor following standard procedure for processing all returning items, but I had an interesting thought : Throwing items, be them flares, clips, grenades, can often clip things along its path. So be careful about this, theres nothing worse than a grenade clipping a wall when you wanted to throw it past it, then getting a face full of shrapnel!"
