There are times when I sneak up on people and catch them completely unawares. I think this would be a good silent knife replacement weapon for a LA. Its killing the enemy with style.
Well they already have access to the masks... Might as well give em chainsaws. This way I can hear them coming a mile away. As opposed to my katana wielding LA. Silent but deadly. Like a Burrito fart in a packed elevator. No one gets out alive.
NC are already part blue, and run around sceaming for "FREEEDOOOOM!! ", so you could give them claymores. The swords, not the mines. Although you could always print "This end towards enemy." down the blade.
