Yandex is good for finding stuff like that, that’s censored on google, but regardless I can’t find anything on that(without more specifics at least ‘American court martialled for refusing order to fire gulf war’ is what I tried), I did find some funny incidents among the horror though:

For example, a Navy sailor was court-martialled for jumping off the carrier Independence while the giant ship was steaming in the Northern Arabian Sea on Aug. 9, 1990.

In addition to being charged with “wrongfully and intentionally” jumping off the ship, the sailor was also charged with resisting a “search-and-rescue swimmer” who was ordered to pluck him out of the water. He also was charged with failure to report to his duty station on the ship.

The unidentified sailor was tried by a special court-martial, but the charge that he resisted rescue was dismissed. On Aug. 28, 1990, after a trial that lasted less than three hours, he was convicted on the remaining charges, and a military judge sentenced him to the brig for two months, reduced his rank, fined him $800 and issued a bad-conduct discharge.

sailor from the Independence was convicted of having 600 doses of the hallucinogenic drug LSD aboard the ship Nov. 27, 1990. His two-day court-martial began Dec. 3, and he was convicted on five drug charges.

These are for refusing to fight but their from the second gulf war https://www.independent.co.uk/news/world/americas/soldier-courtmartialed-for-refusing-to-fight-in-oildriven-war-61225.html
