Okay, this isn't so much a trick as a failed attempt at one. Like many players taking their first spin on the wheel of pain that is Halo 2's Legendary difficulty setting, I got hung up on the second hangar bay. All my marines were dead, all my weapons empty, all my grenades gone, and there were still about a half-dozen Elites pacing back and forth behind the portable shields. One of them wielding a sword.
