To help bolster the work of SACO, Admiral Ernest J. King ordered that 120 officers and 900 men be trained for "Amphibious Raider" at the Scout and Raider school at Fort Pierce, Florida. They formed the core of what was envisioned as a "guerrilla amphibious organization of Americans and Chinese operating from coastal waters, lakes and rivers employing small steamboats and sampans."
While most Amphibious Raider forces remained at Camp Knox in Calcutta, three of the groups saw active service. They conducted a survey of the upper Yangtze River in the spring of 1945 and, disguised as coolies, conducted a detailed three-month survey of the Chinese coast from Shanghai to Kitchioh Wan, near Hong Kong.
The SEALs quickly gained a reputation of being unstoppable and were both feared and respected by the enemy. Today's SEALs continue to operate at the highest levels of professionalism. Their courage in taking down Osama Bin Laden and other feats in the Middle East is unparalleled.
