Mine would have to be the scene which starts of the level in Halo 3 "The Ark".
Nothing says "badass" more than having the Elite ships engage the Brute ships whilst the humans drop onto the Ark.

My heart literally skipped a beat when she got shot and then the music played and you saw the desperation of Noble Team trying to cover her and get her in the bunker. One of the best things of Reach.
