Commando

 is a souped-up version of Mulligan's cronies found in the bunker, There's Fighting in the War Room Part 1.

Attacks
These undead elite warriors are armed with a sabre and an assault rifle. Their close range attacks are damaging, but the sustained automatic fire can quickly turn an enjoyable romp into a hellish experience.

Strategy
The strategy here is to keep dodging. The commandos are nasty and pack a mean punch. Worse, multiple ones can open fire on you and the crossfire is enough to kill even the best hero. Dashing works wonders, as does closing in for close combat and pummeling them into kibbles and bits.
