Tier 3 equipment remains the standard across the force. The service rifle for the Army was first fielded in 2008 and has seen little alteration or experimentation since. Tier 2 tanks are in service in only one battalion of the (Sep) Tank Brigade in Rykkburgh. There is no spare inventory of tier 2 tanks in reserve. Artillery systems lack computerized fire controls due to a budget concerns, with a focus on analog fire controls by necessity. Air Defense Artillery (ADA) battalions lack sophisticated radar to alert and inform commanders of the air threat in the area of operations. Surface to Air missiles are in low supply, most ADA units are focused on gun employment limiting their effectiveness to enemy helicopters.
