And thinking of the Reserves generally, nobody has mentioned the ground forces.
When I served in the US military [a million years ago], every enlistment was for 6 years. Your contract stipulated how much time was active duty and how much was in the reserves. We had a thing called the Individual Ready Reserve a category where you didn't have to do join a Reserve or National Guard unit, but had to keep DoD informed of your address in case of national emergency.
What's more, during the Korean War veterans of World War II were recalled en masse and fed into engaged units in theater. With decidedly mixed results. Harry Truman was on record as saying that he absolutely hated recalling combat veterans from an earlier war, feeling strongly that they'd served their time, but that the conscripts of 1950 desperately needed the veteran's experience, especially in the officer and NCO billets.
So using that as an example, it isn't unreasonable to think that a former United Armies or Imperial Marine Force veteran in their first term after service might be recalled to the colors. In the case of United Armies troops, if they report to their homeworld they're assigned to their old regiment as a wartime filler. If they report to the nearest Imperial facility, they're treated like the Imperial Marines and assigned where the needs of the service dictate.
No matter what previous service, if a veteran is serving in a mercenary unit and that unit is taken up en masse then they serve with their employer.
