A rare deadstock CISO produced Indigenous Rucksack. Conrad 'Ben' Baker of the Counterinsurgency Support Office (CISO) designed the indigenous rucksack based on a VC/NVA design on request of the Special Forces in Vietnam. The bag was intended to be used by CIDG troops hence the name, over 350,000 were produced.
The rucksack was made from rubberized cotton canvas that was water resistant, the CISO pack had a thin waist strap (often cut off as in the case of this rucksack) and featured three outside front pockets and a back map pocket inside the flap. Though designed for indigenous personnel and their advisors, the rucksack was also popular with SOG Recon teams before the Tropical Rucksack become a more common item.
These would have come under the auspices of Ben Baker, Deputy Chief of the U.S. Counterinsurgency Support Office (CISO) and have been part of the various sterile unform and equipment items produced in Japan to support SOG.
