So I was doing a search for NATO camouflage, and ran across the official US Army documentation for camouflaging vehicles. So...
...go here:
https://www.logsa.army.mil/etms/find_etm.cfm
...and enter
43-0209 in the "Pub Number" field and click "Search".
You'll then be at a download page, where you can download the 15.8MB PDF file which outlines camouflage patterns for just about every modern vehicle the US Army uses.
Enjoy!
Note: It's 407 pages, so you might want to double-side it if you're printing.
