The Commando is a type of zombie that appears in DOOM 3 and its expansion DOOM 3: Resurrection of Evil. One of the tougher enemies encountered in the game, this creature differs significantly from the other zombies that appear throughout the game. These monsters were once human Marines that have been transformed into undead killing machines after being possessed by demonic forces. There are two particular Commando variants: the Tentacle Commando and the Chaingun Commando.
Tentacle Commando[]
The Tentacle Commando is a muscular humanoid creature with grey necrotic skin, wearing grey-green combat trousers and a helmet resembling a German Stahlhelme. Its right arm has mutated into a muscular, whip-like tentacle which it can use to attack or to tether itself to objects.
When encountered, the Tentacle Commando will charge at the player full speed, using its tentacle arm to help it cross terrain if it needs to. Once up close, it will attack the player with a rapid series of punches and kicks, or by whipping at the player with its tentacle. If the player crouches down, then they cannot be harmed by the tentacle, but are still vulnerable to the Commando's other attacks. These creatures are impossible to shake off, so they are best dispatched with either the Chaingun or Plasma Rifle.
Chaingun Commando[]
The Chaingun Commando looks very similar to the Tentacle Commando, but has both of its arms intact and carries a Chaingun to kill off victims from a distance. Once the player is in range, it will fire its weapon in a prolonged burst, only stopping if the player manages to get out of range, at which point it will pursue the player and then start shooting again. Dealing with this enemy will often require making use of cover. Once again, the Plasma Rifle or Chaingun are the best weapons to use against it, or the Rocket Launcher since this monster will normally stand far enough away that the player won't suffer splash damage from the explosion.
