The TAP 47/56 was the final version of the French TAP smocks. It did away with the impractical beaver tail and small slanted hand pockets of its predecessors, replacing the lower pockets with much larger and easier to manufacture straight square pockets. It retained the loose cut, snaps, and zippers of previous TAP smocks. The 47/56 model was primarily in the Algerian War by French paratroopers and commando units, but was also used in small numbers by a variety of other countries, including Israel, South Africa (very limited Recce use due to training exercise in France; photo [page 32] and info from Recce: A Collector’s Guide To The History Of The South African Special Forces by Matthysen, Kalkwarf & Huxtable [ISBN 13: 9781920143411]), and US LRRP, often from contact with French forces.
