The Regular Army is the protagonist force from the Metal Slug Series.

It is a world government coalition force used for various tasks. However, they never try to avoid direct conflict, working more without diplomacy. Because of this, they will work through many of their special operation squads and intelligence divisions, even hiring mercenaries if deemed necessary.

They are at war with the Rebel Army for the most part.

The Regular Army is known for its large and varied Slugs (mechanical, animal, or stolen) and weapons.

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