In Grenada and Lebanon, USMC M60s wore the 4 color MERDC camouflage (although
in different colors than typically seen on Army tanks -- the photos I have look
like OD 34087, Medium Green 34102, armor sand and black, but those are just a
guess). Some of the USMC tanks that arrived in Saudi Arabia in 1990 still wore
this scheme (my guess is that those were the tanks that came off the MPS
ships). By the time the war actually started in 1991, it appears that all had
been repainted in one of the shades of sand that appear to have been used.
