The “Stair step” pattern on this jacket is meant to mimic light shining through foliage, and was NOT designed by computer. It is a derivative of TTsMKK pattern available since WW2.
Jacket is named but has no legible internal markings.
Area behind collar has buttons for hood to attach to.
Upper chest pockets are actually 2 small compartments, not big bellows pocket and has red synthetic reinforcement material.
Long velcro strip on arm pocket makes it hard to open arm pockets quickly; velcro arrangement is similar to that on chest pockets on Rhodesian 1st Pattern SAP Jacket.
Waist is elasticated.
Hammer and Sickle on larger buttons.
