Air Rage (2001)

When a Marine Colonel orders his men to massacre a village they were sent to rescue some hostages but when they found them dead they decide to get some payback. Upon returning to the States the Colonel would be court-martialed and made a plea agreement wherein all the blame is on him and his men would be discharged and receive any benefits they’re entitled. But the General presiding over his trial chooses not to agree to the agreement and throws the book at the Colonel and has his men dishonorably discharged thus eliminating all their benefits.
