the armored guardsmen

[3dman27]

in the iron man comics si employee kevin o'brien created his own exo skeleton which he named the guardsman.
after he was killed in action tony stark presented the armor to his brother mike who was acting as the executor to kevins estate ,mike used it as a super-hero most notably as head of security at project pegasus .while there his government superiors confiscated the guardsman armor citing national security and used the suit as a template to mass produce the suits for a unit of federal marshalls assigned to deal both with super criminals and renegade mutants ,as at the time use of the sentinel robots had been declared unconstitutional
what i'd like to know is what happened to the guardsman unit does it still exist or was it dissolved?
