The Mark XXVIII Armor (codenamed "Jack") was Tony Stark's twenty-eighth Iron Man suit and was specialized to withstand high radiation environments. It was a part of the Iron Legion. It was destroyed by the Clean Slate Protocol activated by Tony Stark during the Battle on the Norco.
The Jack Armor was called, along with the rest of the Iron Legion, to help Tony Stark and James Rhodes during their fight against Aldrich Killian and his Extremis Soldiers. During the course of the fight a number of armors were destroyed, though they eventually managed to eliminate all of the Extremis Soldiers.
The Jack Armor has the ability to protect its user from high levels of radiation. The armor also has average repulsor capabilities.
