HTK-AS99 US Army paint set (MASSTER & DUALTEX)
Colours of US Army Europe vehicles from 1970s till 1980s
So-called "MASSTER" camouflage, a predecessor of MERDC scheme, was developed in early 1970s within Modern Army Selected Systems Test, Evaluation and Review project (hence it's commonly used name). It was widely tested by units of United States Army Europe (USAREUR) based in West Germany. The scheme was used through late 1980s (and in some cases well into the 2000s).
The Dual Texture Gradient Patter or "DUALTEX" camouflage was another experimental scheme, tested between 1978 and 1985 on vehicles of 2nd (US) Armoured Cavalry Regiment deployed along inner German border. The scheme itself followed standard MERDC Winter Verdant colours, but used them in form of square shapes - in this way it was predecessor of modern digital / pixel schemes.
