Imperial 203rd Aerial Mage Battalion is a reinforced Aerial Mage Battalion led by Lt. Col Tanya von Degurechaff under the Salamander Kampftgruppe(under the shell formation Lergen Kampftgruppe), reporting directly to the Imperial General Staff. It consists of 48 active men with powerful Elinium Type 97 Dual Core Computational Orbs that is capable to fly more than 12,000 feet above sea level and almost equal Tanya's firepower and mana efficiency with the Being X enhanced Elinium Type 95 Quad Core Computational Orb.

However, due to their high level of skill and coordination in addition to their unusually powerful orbs, the unit is often mistaken for a regiment of over 100 mages, simply because the other nations are incapable of imagining a unit this small doing this much damage.

They are also, in principal, their worlds first special forces unit.
