Between June 1969 and March 1971, I served as a Special Agent with the Navel Investigative Service, Bldg. 200, Washington Navy Yard. They had just changed the name from ONI. My diploma from the basic investigators school says ONI. My issue weapon was a round butt, 4" Model 19, Smith. Everyone had one.
My supervisor had just returned from Vietnam and he said that they had the same M-19s but they were parkerized. It was a neat piece.
In January 1971, the intelligence community country wide took a budget hit from Congress because they said we were spying on Americans. The Naval Intelligence Command received a 125% reduction in funds. They dropped that reduction on Naval Investigative Service.
As a result, at the end of our basic school, 150 Special Agents were RIFd. Having a good bit of service time, I was last off. But off never the less. - 'ole joe.
