CISO (Counter Insurgency Support Office) headed by Deputy Chief Ben Baker and located on Okinawa provided many logistical resources to MACV-SOG and Special Forces during the Vietnam War.  Among these items were sterile uniforms to be worn by US and indigenous SOG personnel on clandestine operations in Laos and Cambodia.  This is an example of a CISO procured shirt patterned to look like an NVA garment.

The only marking it bears is a number “3″ inside the collar, which may denote size.  There is ample photographic evidence of this pattern CISO shirt being worn by indigenous RT (recon team) SOG members in books like:

• SOG: Team History and Insignia of a Clandestine Army by Jason Hardy and Mike Tucker
• Running Recon: A Photo Journey with SOG Special Ops Along the Ho Chi Minh Trail by Frank Greco
• SOG: A Photo History of the Secret Wars by John L. Plaster
