Narrative:
Aircraft X was part of a flight of 3. They were out of 12;000 descending into mwh airspace; mwh had assigned 050 and coordinated an unrestricted descent. Aircraft X could no longer see the other flight members; and began a climb to FL200. Mwh approach called and informed us of the deviation; but the aircraft climbed very fast and didn't notify anyone until well after. There was no traffic there; but there easily could have been [another aircraft] climbing out of geg or landing lws lower than FL200. Aircraft X did not follow appropriate protocol or declare an emergency in this situation; leaving mwh approach and sector 18 unaware.[I request] that the military follow proper protocol for breaking apart a flight in these conditions. They were never assigned FL200; so why they chose to climb that high is very odd and dangerous.
