Yes. They were made by ARMSCOR and used by the Recces on ops in foreign countries. The program was highly secret for the obvious reasons! I've been meaning to make a more thorough post on the topic, but haven't had the time. Gilles seems to have beat me to it.
nope all long gone. I forgot they also had t-shirts in rain pattern (and t-shirts in port. pattern as well) as well. I had pretty good friend back in the 80s who was ex rhodesian army and then went to the recces when the SADF extended contracts to Rhod security forces after zim independence.
