The main item missing from the decal sheets is a suitably sized Squadron marking to fit on the tool box. Luckily, the Rubicon M5A1 has a very small US Invasion star, which just about fits. One of them had the star cut out, the other had the star left in but painted over afterwards.
This is the painted over one (the tow wire needs some tidying).
And this is the one with the star cut out.
The division insignia and tactical sign are from the Warlord British Guards Armoured Division decal sheet.
Now for some tidying up then shading and weathering.
