In "Front Mission", players use playable units called "wanzers", a term for mecha derived from the German word "Wanderpanzer", or "walking tank". A wanzer differs from the typical combat unit in that it has four modular parts: body, left arm, right arm, and legs. Each part has a specific function and its own health bar. The legs parts enable movement and evasion, the arm parts are necessary to use hand and shoulder weapons, and the body part maintains the wanzer's operability. In the event the body is destroyed, the wanzer is removed from play completely. Destruction of arm and leg parts does not remove the wanzer from play, but it severely cripples its performance. While the player fights mostly wanzers, vehicles, aircraft, and mobile weapons platforms are also featured. These enemy units generally have only one part, the body, and are much stronger than wanzers themselves.
