Coastal Security Service  -  Sở Pḥng Vệ Duyên Hải.

In January 1964, at Da Nang, central Vietnam, along the South China Sea,
Coastal Security Service was founded and commanded by Major Ngo The Linh
with operational support and planning by MACV-SOG Maritime-Operation (OPLAN 34A)
to conduct top secret commandos raids to North Vietnam using high-speed boats.

Colonel Linh counter-part was the late Lieutenant Colonel Robert McKnight.

These commandos raids lead to the Gulf of Tonkin "incident" in August 1964.

The commandos were known as "Biet Hai" or Sea Commandos.
They were courageous volunteers whom had no fear of death,
willing to go at moment notice without reservation.

Biet Hai was a very highly trained, top-secret elite group of volunteers.
Many had perished in South China sea while attacking the North Vietnamese.

This page and Biet Hai website  serve to honor
these unknown fallen Heroes of  SPVZH/CSS.

Colonel Ngo The Linh commanded SPVZH until July 1966
then transferred to Vice Admiral Hồ Văn Kỳ Thoại.

My gratitude to Master Sergeant Kenneth Mancil, US Army, Retired
for providing these rare pictures of Paradise Island in 1967.
Rare, because of the top-secret nature of  CSS Mar-Op.

I think the pig was purchased from the islanders.  Not sure.

The team house had been refurbished by a team of Phillipinos and Vietnamese Craftsmen.
They split bamboo for the trim and it was beautiful.
 The head man was named Sarabia and was a very nice guy.

Captain John Robbins and Ron Kauffman
 This may have been prior to our closing down operations-
 When the bombing of North Vietnam was halted; 
our operations North the the 17th Parallel were halted also.
We had a farewell party with our friends from CSS. 

This is some sort of celebration dinner - It was time to relax.
