Firstly, is it all one colour, and the tank, mudguards and toolboxes are one green lined with gold, whilst the biscuit tins, engine, frame, forks, caskette and crash bars are a slightly different green.
I did ask the factory, but got no reply, and I have no idea of there is a standard army colour that they use, of if they just chuck some green together whenever they decide to make these.
For tornado, my 1994 home market military, I have never managed to match the gold lined green, but the engine and frame green If you are in the UK then it seems to be equivalent to Humbrol 116 MATT US Army Green. Spray some halfords lacquer on the top, (the ‘mid’ one, not the gloss or matt) and within seconds, the paint changes colour a little and blends in almost perfectly.

Of course, you could repaint the whole thing!
