Most US Navy vehicles I have seen from that era were painted a medium grey with the words "US NAVY" and a ID Number underneath it.
The middle truck in the below picture is a Navy GMC 2 1/2 ton CCKW.
And a 3/4 ton Dodge panel truck;
A Chevrolet 1.5 Ton Cargo truck:
A couple of Navy Jeeps
Those should give you enough referances. Good luck.
