The Regular Army (正規軍 Seikigun) is the protagonist force of the Metal Slug series.


The Regular Army is the main armed force of the World Government and is composed of various coalition forces from around the globe. They mostly try to avoid direct conflict, mainly resorting to gathering intelligence, deploying special forces behind enemy lines, even hiring mercenaries if deemed necessary. They are at war with the Rebel Army for the most part and are trying to maintain world peace while fending off numerous supernatural and alien calamities.

The Regular Army is also known for its large and advanced Super Vehicles (mechanical, animal, or stolen) and their advanced experimental weapons.

The Super Devil seems to have taken an interest in the Regular Army. It offers them aid but only at extremely dire times.


The Regular Army only has two main uniform colors: light-blue which is the standard one and grey for urban combat. Special operatives also wear tactical gear and/or various camouflages depending on their missions.
