Imperial Army Space Force

The Imperial Army Space Force (帝国軍宇宙軍) is the space-borne branch of the Imperial Army. The smallest branch of the Imperial Army, the Space Force is primarily a supporting arm of the Imperial Army responsible for interplanetary transportation of the Army's planetside assets. To this end, the Space Force mainly consists of the Imperial Army Space Transportation Force. The Space Force is also the parent branch of the Orbital Divers, the Imperial Army's elite spaceborne strike force.

The Space Transportation Force is responsible for the transport of land forces between planets as the inter-service rivalry makes acquiring Imperial Navy transportation a tedious process. It is the only Imperial Army branch that operates large starships in space, and is responsible for not only basic transportation but also for maintaining interstellar and interplanetary supply lines for long campaigns.
