Combat is an early video game by Atari for the Atari 2600. It was released as one of the nine launch titles for the system in October 1977, and was included in the box with the system from its introduction until 1982. Combat was based on two earlier black-and-white coin-operated arcade games produced by Atari: Tank (published under the Kee Games name) in 1974 and Anti-Aircraft II in 1975.
