The Marauder Bomber is the primary atmospheric bomber aircraft used both by the Alliance Joint Military and later the Imperialist alliance. The aircraft is usually based on an orbiting starship, and can operate in the vacuum of space as well as in a planet's atmosphere. During a prolonged Imperial campaign, Imperial Navy airbases can be established on the ground, but due to the Marauder's extreme range they are located safely behind the front, sometimes even on another continent from the frontlines. During ground assault missions, the Allied forces on the ground will mark the enemy's positions with coloured flares. Sometimes experienced allied pilots will accompany the ground forces to better coordinate air strikes.
