LOL I just thought of something. Heh, HUMANS invented the damn thing to make sure people didn't die from "friendly fire". And now some rookie humans are whining about using it. Heh, some join the military because they want to actually help preserve the peace and help protect lives, some join becuase they want to fight, and some join because they've got a hidden taste for blood and want to sate it without turning into monsters.

Now we can see who's who via the instruction. :-)
