Mannequins are recurring object that has become synonymous to the Black Ops series and the Nuketown series of maps. Originally seen in Call of Duty 2 in the levels "Red Army Training" and "Demolition", Call of Duty: World at War in the level Vendetta and the map Revolution, Call of Duty: Modern Warfare 2 on the map Storm, Call of Duty: Black Ops on the maps Nuketown and Hazard, Call of Duty: Black Ops II on the maps Nuketown 2025, and Nuketown Zombies; and in TranZit mode, Call of Duty: Black Ops III on Nuk3town, Call of Duty: Black Ops 4 on the multiplayer map Nuketown and on the zombie map Alpha Omega, once more appearing in Call of Duty: Black Ops Cold War on the multiplayer map Nuketown '84.
Call of Duty 2
In "Red Army Training", Commissar Letlev will tell the player to melee a mannequin. It is dressed with a German uniform and helmet. Later in the second room in Demolition, Pvt. Koslov moves with his group through an abandoned Stalingrad apparel store, featuring fragmented and whole mannequins.
Call of Duty: World at War
In room of the sniper battle in the level "Vendetta", the mannequin is used by Sgt. Reznov to draw the fire of the enemy sniper. Sometimes they are wearing German helmets and sometimes they are not. In the map Revolution which is based off "Vendetta", the same mannequins can be seen. In the Nazi Zombies map Verrückt, there are two mannequins; one with several knives pierced through it, and one hanging from a noose over a fallen chair.
Call of Duty: Modern Warfare 2
In the multiplayer map Storm, 50 undressed mannequins can be found. A few players rather new to the map can occasionally be seen firing at the mannequins thinking they're enemies in the low lighting.
Call of Duty: Black Ops
On the multiplayer map Nuketown, mannequins are found in random locations all over the map, in and out of the map's boundaries. A mannequin's head and arms can be removed by any means, gunshot, knife or otherwise. On the multiplayer map Hazard, mannequins can be seen dressed up in golf gear in certain buildings. In the Zombies map Kino Der Toten, they can be seen in the Dressing Room.
Call of Duty: Modern Warfare 3
Call of Duty: Black Ops II
Mannequins are found in random spots all over the Nuketown 2025 multiplayer map. They also appear in Zombies. In Nuketown Zombies shooting or knifing all their heads will play an 8-bit version of Coming Home. The torso of a mannequin is also used to build the turbine in TranZit and Buried.
Call of Duty: Black Ops III
Mannequins are found scattered around the map on NUK3TOWN multiplayer map. If all the mannequins' heads are shot off within the first two minutes of a match, they will come to life and chase after the player in a similar manner to zombies. If all their arms are removed within the first two minutes, they will still come to life, but behave differently, moving only when the mannequin is mostly or completely out of the player's view.
Call of Duty: Black Ops 4
However within Alpha Omega the Mannequins take different role as they are not merely mannequins, but a prototype of an android known as an "A.D.A.M. Unit". There are three Easter Eggs involving the removal of each of the heads of the A.D.A.M. units in the map, doing so by shooting will cause the next round to consist of only A.D.A.M. units that have greater health than standard zombies. Knifing the heads off them all will cause a male A.D.A.M. unit to follow the player in a fashion similar to Weeping Angels from Doctor Who, this unit can be lead to female A.D.A.M. unit in the Generators to garner a reward. The final Easter egg involves meleeing all the heads with the Galvaknuckles equipped, doing so will spawn a A.D.A.M. unit beside the Pack-a-Punch Machine, which will cause a jumpscare if aimed at.
Call of Duty: Black Ops Cold War
Mannequins return in Call of Duty: Black Ops Cold War, added in with the addition of the Nuketown '84 map. Shooting the heads off all the mannequins will change the players view into a synth style and start the song "Storm Surge" by Brian Tuey. It will also unlock the song for use in the Music Player.
- In Nuketown, if all of the Mannequins heads are shot off within the first 15 seconds of the match beginning, the Rolling Stones "Sympathy for the Devil" will play over the loudspeakers.
- Mannequins can also be found inside of the school bus, however these mannequins do not need to have their heads removed for the song to play.
- If a mannequin's head is shot off with a Crossbow, Ballistic Knife, or Semtex, the mannequin's head will fly off, however the arrow, knife, or Semtex, will still be where it was inside of the Mannequin's head.
- In the house similar to the Brady Bunch home, two mannequins can be seen out of the window, and they appear to be holding hands, visible only if in Theater Mode or spectating.
- The German Sniper's use of Mannequins as decoys in "Vendetta" is a reference to the film Enemy at the Gates.
- If one of the easter eggs involving the mannequins is activated in NUK3TOWN, when the match ends, all the mannequins will be frozen in the same position and place they were in before it ended.
