So I was playing CE, and I thought, "man, these Reach DMR, AR, and magnum models are great, but the animations aren't game-accurate like the H3 weapons." So, what I thought I'd do is, I'd make a video that systematically displays all of the weapon animations so animators that want to replicate Reach weapons can watch the video frame by frame in Reach's theater mode and copy them! Genius!
I made two videos, one for spartans and elites. I know they're not perfect. I messed up doing the animataions in order for a few of the weapons, I forgot to do grenade throwing animations for elites (they're the same as spartans anyway, so it doesn't really matter too much), I sometimes cut off the first empty reload animation of each weapon (the second one isn't cut off), and I kind of mess up keeping the weapons organized when I try to show the initial pickup animation. Still, I think you animators out there will find these useful. If there are any animations that are unclear (there probably are), PM me and I'll make a new video for you.

What you really want to do is download it to your Xbox, then watch it frame by frame on there, because you can't play it slowly with Silverlight.

Yep, sadly not everyone has an xbox, nor reach.
