lol you got this from >BLOC
Went around on the forum a little bit, found this.
It's apparently a thing for arming your nation's soldiers.
anyway:

also seeing as more than half the guns weigh nothing for no apparent reason, I wouldn't trust the weights it gives out for soldiers.
Also, you see those knives with rope? Those are for climbing and/or being used Indiana Jones style on someone. They do make nice, silent weapons, so why not?
or I could make them be fired out of the grenade launcher
