These solid colored uniforms were produced for the South African Special Forces during the Border War. Like other Recce-specific items, these were almost completely sterile with only minimal markings for size; the “official designation” is unknown.
The green colored version appears to be the most commonly available on the market and most commonly seen in photos.
Green Version:
The green version is made from a herringbone twill (HBT) material.
Jacket:
Generic 4-pocket jacket with an obvious resemblance to the US M65 and other M43-derived field jackets commonly in seen in military use. No markings remain on this example. The jacket is probably the most commonly encountered part of this type of uniform.

Usage Photos:
Due to the clandestine nature of Recce operations, very few photos show this type of uniform in use.
