They would own inf (Like Burton's Knife); stealthed when walking or not moving, un-stealthed when they stab someone or run. Can disable enemy buildings like a sabotage.
Would be like the equivalent (however crapper and much cooler!) to USA's snipers.
To be honest, this idea would be cool in Shw or RoTR too.
EDIT: Perhaps they could be upgraded to be equipped with a Wet Fish... which would be anti-tank.
