- "Heavily armored quadrupedal combat robot. Can be remoted controlled."
- — Description
The Mantis is a quadrupedal drone that can either roam around the map and fire missiles at enemy players, or be controlled by the player. It was developed in 2038, with another version of the Mantis spouting a yellow finish being developed in 2040.
When activating the Mantis, the player will equip a Mantis Marker that utilises the model of the Smoke Grenade. Once the marker is dropped, a small package containing the robot will be dropped into the map via a helicopter.
- In the map Arsenal, Diaysler Robotics is shown to have created the Mantis, which is also a successor of the A.G.R. from Call of Duty: Black Ops II.
- The crate that holds the Mantis is reused from the Cerberus scorestreak from Call of Duty: Black Op III, and thus has the words "Cerberus" on the model.
- In the Multiplayer Beta trailer, the Mantis is shown with a full-white colour scheme that went unused in the full game.
