Similar to how the failed FA-78-1 Full Armor Gundam was meant to enhance the offensive capabilities of the original RX-78-2 Gundam, the FXA-03 Full Armor pack for the Mk-II was meant to add greater offensive and defensive capabilities. The new armaments included one head-mounted Vulcan pod, Grenade Launchers on its forearm, and a 2-barrel Beam Cannon with an attached Grenade Launcher.

While the Full Armor pack did increase the Mk-II's offensive and defensive capabilities, the FXA-05D G-Defenser however had a more well rounded armament and did not weigh down the Mk-II in combat, so development was focused towards the G-Defenser and the Full Armor pack was never used.
