I was in 82nd at the time.
I bought my own lite, a Surefire GII Nitrolon in OD Green, shaved down the body so it would fit inside a Weaver ring, clamped it to my KAC RAS.
I also bought a Red lens filter for it, and colored it black for use with NODs.
One of the other Squad Leaders in my Platoon bought an L60 with tape switch and an $85 Surefire IR filter.
Some of the Joes had GIIs also.
My M4 is not representative of any of the others in my Brigade at the time though if you look at the stock.
I got that from Land Warrior Test Platoon, a leftover, which later became standard. Everyone else had Colt Fiberite telescoping stocks.
This is from February or March of 2003 out on Failaka Island in the Persian Gulf where we did endless CQB in real homes that were fully furnished. Some Marines had been gunned down there right before we arrived. This was before the air war even kicked off.
The only people that I saw at the time with Surefire M951s were in SOCOM, unless you bought one yourself.
ODA's used to buy those in 12s from approved local businesses.
