hmer,
I would say that it is one of the following:

Federal Standard 595 numbers FS30277 (which I heard is exactly the Desert Storm color,but I heard this might be a discontinued color)

In case it is, the replacement could also be this
Federal Standard 595 Color FS 33446
based off the picture I saw, but then again it could be my computer

I also found this for you in case your buddy wants to mix paint

Military vehicles are painted with water dispersible CARC paint using Federal STD-595B color 33446 "Desert Tan." The performance and composition specification is MIL-DTL-64159 which defines Tan 686A, 33446 with these parameters:

Brightness Y 0.360 ? 0.400
Chromaticity x 0.368, Chromaticity y 0.364
Infrared min 62.0, and Infrared max 72.0

The same Desert Tan 33446 color is sometimes referred to as Tan 686 or Tan 686A. As an alternative, if 33446 Tan is not available, Sand 30277 or Sand 33303 are sometimes used. The Desert Tan 33446 paint is available in quite a few types of packaging (from 55 gal. drums to spray cans) and is also formulated as other types of paint than CARC.

Hope this helps
