OAA III

Main Battle Tank OAA III Orbital Assault Armor Type III – of the United Stars Marine Corps (identical to the Assault Crab Type III of the United Stars Army) First Units delivered to the United Stars Marine Corps in 4790 – Last Units decommissioned in 4890 Used during the Union / Pertharian war as a Recon device, rather than a MBT. The OAA III is a Walker tank capable of flight. The walking mode requires much less energy and allows the Signature dampers to camouflage the tank much better. A skilled OOA operator can move the tank almost completely soundless across most terrains. This ability earned the machine the nick name Sneaky with the Marines, and Silent Terror with the Pertharians who were quite often completely surprised to find a squad of OOAs at almost point blank range within their positions. These tanks are also known as Spider tanks or Walker tanks. The OAA III – Manufactured by SII was well liked with the troops ,as it had two added arm manipulators giving it field engineering capabilities.
