The Rogan Commandos were members of Thomas Rogan's secret division. During a raid of the EFI Research Facility, they were killed by the biologically-engineered creatures inside, and subsequently reanimated. They retain their strong fighting and agility, attacking either with dual combat knives or leg kicks.
They wear the same outfit they wore after they were consumed by the undead but their lower left pants have been torn off along with the respective knee pads and boots. The lower part of their shirt sleeves have been torn off as well. There are scars on their uniforms and caps which seem to correspond to slashes done by knives. Though they have long used up all the ammunition from the shotguns they held when storming the building, they are still lethal with quick side-by-side movements, dual combat knives and left leg kicks.
One Rogan Commando named Yukio, who is killed in Chapter 0, serves as a miniboss in the final chapter and can take far more damage. Interestingly enough, unlike the other creatures in the game he can talk, though it appears that he just says random phrases he once said when he was alive like "We're humanity's last hope, we can't lose" and "That was for my buddies!".
