CISO
The Counterinsurgency Support Office was established on Okinawa in 1963 to supply clothing, weapons and equipment to
Special Forces operating in Vietnam. Principally run by Ben Baker, the office issued standard and untraceable (sterile) gear as well as locally developed items such as the
bolo knife, the
indigenous rucksack, tiger stripe fatigues and
Viet Cong style
black pajamas.
