One of the first items the US military upgraded with MDC armour plating was of course the M1 Abrams. This was due to the fact manufacturing capabilities were not quite up to snuff in order to maximize the potential of the new super hard/tough materials. Dubbed the A4 model it featured some other useful upgrades as well such as solid oxide fuel cell technology and a standard upgraded sensory package. Its speed and range were both increased along with the added protection of MDC armour. Its one drawback was it was not a completely MDC constructed vehicle so it did not provide the same kind of protection the later A5 model would. The A4 served along side the A5 until the A5 was fully deployed in the late 2060s. Most had been mothballed or had been transferred for use by the Army Reserves, but a fairly large number also found their way into the hands of poorer nations, where they held their own until the introduction of power armour and smaller robot combat vehicles.
