actually i agree with the other guy. they are pretty much invinceable except for a few of them. the robot sarge guy. he SUCKS! he died in like 15 minutes. i also had the supermute and currently i have this ghoul merc. hes beastly. i have him in tesla armor witha combat shotgun and he kills supermutes in 2 hits. death claws are a strugle for him. he killed 2 by himself though. he had 2 bars of health left also. but also. if he just stays out of battle for 48 hours or so he regenerates all his health. oh anddd. i had him in the capitol building where the supermute was and all the talon mercs were dead so i like him kill the supermutant bohemoth all he did was stand in the doorway and he took him out. that easy..
