What do UNSC Air Force SF look like?

[UNSC Marine Lt]

I was thinking about the mission Long Night of Solace the other day, and I've always considered it a bit odd that its exclusively Army personnel defending the launch facility. I would expect to see AF security forces, as that is their job (I also think it would have helped reinforce that this is the UNSC's home planet). That set me to thinking; maybe I should make a security forces kit. They definitely see action in Halo, and it'd certainly be a unique project. The Air Force is chronically underrepresented. There's one small problem: we have absolutely zero depictions of Air Force ground troops in the series. We know they exist, we just never see them. This means we have to brainstorm it.
So, here's what I was thinking:
- standard trooper armor (no shin guards).
- the drab teal uniform we see the pilots wear.
- black boots.
- air force insignia
I feel the use of the teal uniform, black boots, and insignia would serve to visibly differentiate it from the Army while the dust brown armor would convey that it's a ground pounder kit, not a pilot. I'm still aways off from making this though, so any suggestions? Thoughts, comments, condemnations? I'm extremely open to ideas and would appreciate input.

(P.S. Does anyone know where I can find a convincing lookalike for the teal BDU? I'm having no luck.)

I used the following concept art as a base for my Pilot build, Reach has a lot of interesting designs

That was always one of my favorite pilot looks, along with the one below it (that entire lineup of reach concept art is cool). However, Reach doesn't provide any concept art for AF ground troops. I'm concerned that a green uniform would make it look too much like the Army.
