Good morning, with reference to my earlier post the Vallejo colour I have used for my Soviets is Russian Uniform (924) and the recommendation I have for the Yanks in all-over green is US Dark Green ( 893). The former was recommended by a friend more knowledgeable than I, the latter I found on a website about US Cold War vehicle colour schemes . I can recommend the Osprey mentioned in an earlier post. It dates from about 1987 and is by Stephen Zaloga who is pretty knowledgeable on these topics.
Whatever colour you use for the US green, it should be exactly the same green that you're using for MERDC-camouflaged vehicles. It was exactly the same 'Forest Green' paint.
In Humbrol terms, I use the following (all with black undercoat and dry-brush in 72 Khaki Drill):
Russian vehicles:
75 Bronze Green base coat with 150 Forest Green highlight.

US Vehicles (MERDC pattern which was applied with varying degrees of success to a standard template for each type of vehicle):
MERDC Forest Green - 116 US Dark Green (also used as the plain colour for M1 Abrams and M2/M3 Bradley)
MERDC Field Drab - 29 Dark Earth
MERDC Sand - 72 Khaki Drill and 34 White in 1:1 mix
MERDC Black - 33 Black


British vehicles:
Green bits (2/3rds of vehicle) - 75 Bronze Green base coat with 159 Khaki Drab highlight.
Black bits (1/3rd of vehicle) - 33 Black with 67 Tank Grey highlight.

Danish vehicles:
Green bits (half of vehicle) - 75 Bronze Green base coat with 80 Grass Green highlight.
Black bits (half of vehicle, including all four corners) - 33 Black with 67 Tank Grey highlight.

West German vehicles:
75 Bronze Green base coat with 155 Olive Drab highlight.

Dutch vehicles:
75 Bronze Green basecoat with 155 Olive Drab highlight (same as Germans).

Canadian vehicles:
Leopards - same as West Germans
All others (standard camouflage pattern):
Base green - 120 Light Green
Green camouflage bands - 159 Khaki Drab
Black camouflage bands - 33 Black with 67 Tank Grey highlight
