Stark began using this armor during the time that he served as the United States Secretary of Defense. Standard weaponry including repulsors, uni-beam and sonics. Concussion blasts were used against the Hand. Zero-point energy was used against Michael Pointer (aka The Collective). Via voice command, the armor could adopt an autonomous, robotic Battle Mode. If separated by magnetism, it could reform and return to Stark. Defensively, a repulsor shield could be extended to protect the armor and allies. Security was enhanced by upgrades to anti-tampering devices.
