I have not seen Air Force M725's. Only M715's. Some in OD, some in 3 or 4 part camouflage.
I have seen Navy M715's, M725's and M726's.
All were OD. Standard USN door markings, plus on the ambulance, markings above the doors on the rear.
Seabees emblem under the mirrors on the doors on the M715's and M726's, and under the markings on the doors of the M725's.
Standard red/white crosses on sides and rear doors like Army M725's.
If you want, I can upload some pics to photobucket and get them downloaded here.
