they would undergo a SEAL Basic Indoctrination (SBI) training class at Camp Kerry in the Cuyamaca Mountains. After SBI training class, they would enter a platoon and conduct platoon training. According to founding SEAL team member Roy Boehm, the SEALs' first missions were directed against communist Cuba. These consisted of deploying from submarines and carrying out beach reconnaissance in a prelude to a proposed US amphibious invasion of the island. On at least one occasion Boehm and another SEAL smuggled a CIA agent ashore to take pictures of Soviet nuclear missiles being unloaded on the dockside. The Pacific Command recognized Vietnam as a potential hot spot for unconventional forces. At the beginning of 1962, the UDTs started hydrographic surveys and along with other branches of the US Military, the Military Assistance Command Vietnam (MACV) was formed. In March 1962, SEALs were deployed to South Vietnam as advisors for the purpose of training Army of the Republic of Vietnam commandos in the same methods they were trained themselves. The Central Intelligence Agency began using SEALs in covert operations in early 1963. The SEALs were later involved in the CIA sponsored Phoenix Program where it targeted Vietcong (VC) infrastructure and personnel for capture and assassination. The SEALs were initially deployed in and around Da Nang, training the South Vietnamese in combat diving, demolitions and guerrilla/anti-guerrilla tactics. As the war continued, the SEALs found themselves positioned in the Rung Sat Special Zone where they were to disrupt the enemy supply and troop movements and in the Mekong Delta to fulfill riverine operations, fighting on the inland waterways. Combat with the VC was direct. Unlike the conventional warfare methods of firing artillery into a coordinate location, the SEALs operated close to their targets. Into the late 1960s, the SEALs were successful in a new style of warfare, effective in anti-guerrilla and guerrilla actions. SEALs brought a personal war to the enemy in a previously safe area. The VC referred to them as "the men with green faces," due to the camouflage face paint the SEALs wore during combat missions. In February 1966, a small SEAL Team One detachment arrived in South Vietnam to conduct direct action missions. Operating from Nhà Bè Base, near the Rung Sat Special Zone, this detachment signalled the beginning of a SEAL presence that would eventually include 8 SEAL platoons in country on a continuing basis. SEALs also served as
