Desert MARPAT is the standard for the USMC.
For the US Army, the new Multi-Cam is the standard.
Most USAF personnel wear their new digital tiger-stripe pattern. Some will wear Army Multi-cam when working with Army units.
The US Navy and USCG still uses the older DCU pattern that was used in '03 though.
