USARPACINTS

USARPACINTS stands for United States Army Pacific Intelligence School, which was located in Okinawa and serviced by APO 331. Below are two covers, one sent to a Vietnamese Lieutenant training at the school, the other from a Vietnamese Lieutenant to Saigon.



Below are two citations that comprise the extent of the information I have been able to locate online about the school.

One unique feature of the Pacific theater was the existence of the U.S. Army Intelligence School, Pacific. Unlike other Army intelligence training facilities overseas, the Pacific intelligence school, set up on Okinawa in 1958, trained foreigners, not Americans. The students from seven different countries bordering the Pacific basin took courses in combat intelligence and counterintelligence techniques until the reversion of Okinawa to Japanese sovereignty brought operations to a halt in 1975.

More tantalizing are the following excerpts that school was linked to "Project X" and potentially the Phoenix program.

Until the early 1980s, the U.S. military ran an intelligence training program in Latin America and elsewhere using manuals that taught foreign officers to offer bounties for captured or killed insurgents, spy on nonviolent political opponents, kidnap rebels' family members and blackmail unwanted informants, according to recently declassified Army and Defense Department documents.

The manuals, known as Project X, were written by U.S. Army experts starting in 1965 for use by the U.S.-funded Joint Foreign Intelligence Assistance Program. Portrayed by the Army as instructional materials to help friendly governments fight Cuban- and Soviet-inspired rebels in Latin America, the manuals were "in fact a guide for the conduct of clandestine operations" against domestic political adversaries including peaceful ones, according to a panel of Army experts that later reviewed some of the material.

Army officials were unable to provide details about the intelligence assistance program, such as the date it ended or the countries where it operated. It's also impossible to tell how the use of the training manuals may have influenced the actions of foreign militaries.

The intelligence assistance program was first used in 1965 to train Vietnamese and other foreign nationals at the then-U.S. Army Pacific Intelligence School on Okinawa, Japan, and also operated in Iran in the late 1970s, according to the records.

"This school is in an excellent position to meet requests for intelligence training submitted by" military advisers and attaches in "the Pacific and Southeast Asia area," a 1965 informational brochure on the program states.

One counterintelligence official told Army officials in 1991 that she believed the program might be linked to the Phoenix program, a U.S. military and CIA undertaking that resulted in the assassinations of thousands of South Vietnamese suspected of disloyalty. Some of the Project X materials appeared to be the same as the Phoenix lessons, and the Army intelligence school was teaching a course on the Phoenix program at the same time that the Project X manuals were being written, she noted.

During the mid-1970s, after the intelligence school moved to Fort Huachuca, Ariz., the school "began exporting, on request, Project X material to MAAGs, MILGROUPS, defense attaches, and other U.S. military agencies participating in the U.S. advisory-training effort in friendly foreign countries," according to a short history of the program prepared in 1991.

The program's history is difficult to trace in part because Defense Department intelligence oversight officials, after seeing what the manuals contained in 1991, ordered that the original documentation be destroyed. The ostensible reason was so the materials could never be used again.
