The US Navy had been recruiting Filipino nationals since the Spanish-American War, but the program was formalized shortly after WWII.
Tens of thousands of Filipinos were recruited. They were the only foreign nationals allowed to enlist in the US Armed Forces, and then, only to the Navy.
The recruitment program was in exchange for allowing the US to maintain military bases in the Philippines (not to mention having fought side by side heroically against the Japanese occupation.)
Unfortunately, they were not allowed into any Navy Rates. They were limited to being Stewards until Adm. Zumwalt changed that in the early '70's, finally opening up most all rates for the Filipinos.
Despite its limitations, the recruitment program was a great benefit and opportunity for those of a war-torn country with a devastated economy and extremely poor standard of living. The program finally ended in 1992.
The Filipinos I knew and served with, to a man served with honor and reflected great credit upon their heritage.
