The Commando, also known as a Heavy Weapon Dude, is a recurring enemy that appears in almost every Doom installment. They are generally the final and most powerful enemy of the former human class.


  • Internally, the Doom source code gives the Heavy Weapon Dude the type name MT_CHAINGUY, in reference to the Chaingun.
  • Called a "Clyde" in the Doom novel.
  • Whereas the Zombieman and Shotgun Guy wear the same basic uniform as the protagonist (albeit different-colored versions) and have similar physiques and, thus, share a common base for their sprite sets, the Heavy Weapon Dude's sprite is unique due to his burly/overweight build.
  • The Heavy Weapons Dude's death animation is also unique among human zombies; while the Zombieman and Shotgun Guy both share the same dying sequence of chest/abdomen bursting open as they fall backwards, the Heavy Weapons Dude's right shoulder and head will burst as his right forearm falls off.
  • Interestingly, when the Heavy Weapons Dude dies, his chaingun can still be seen as part of his corpse, despite him dropping the gun upon his death (which makes sense when just grabbing ammo, but if it is the first time the player has found a chaingun and takes it, it does not make sense).
  • Final Doom's The Plutonia Experiment has the highest number of Heavy Weapons Dudes used in a single mainstream Doom title; almost every single level has them, with the sole exclusions being MAP11: Hunted (since it only contains Arch-viles as enemies).
  • The Heavy Weapons Dude is one of the three enemies whose machine gun sounds like a shotgun being fired rapidly, along with the Wolfenstein SS and Spiderdemons (this behavior actually makes sense for the Spiderdemon, since it fires three bullets per shot, similar to the Shotgun Guy's shotgun--however, this behavior was probably applied by accident to the Heavy Weapons Dude and SS). In the PlayStation and GBA versions of Doom, his gunfire noise is "corrected" to sound the same as the players'.
  • In a ZDoom-based source port, if the player is killed by a Heavy Weapons Dude (monster is credited with delivering the blow that reduces the player's health to 0%), an obituary message is displayed at the top of the screen: "[player name] was perforated by a Chaingunner".
  • In the PlayStation and Sega Saturn ports, Heavy Weapons Dude can appear in the original Doom levels on Ultra-Violence. In fact the first time it appears is MAP01:Hanger.


Doom RPG[]

In Doom RPG, the Heavy Weapon Dude appears as the "Commando" monster class. There are three variations, identified by color:

Their attacks are capable of destroying jammed doors, much like the axe does, and will attack three times consecutively. They are weakest against plasma attacks.
