Seal Team #1 was close to my unit during my stay on Coronado 1967 to 1971. Those men carried telephone poles over their heads most of the day. In and out of the chow hall in a couple minutes. We practiced beach landings with them on the ocean side of the strand. In shape bunch of guys. Finely trained in special ops.
Over time other teams have been added to the base, #3, #5, #7. The odd numbered teams on the west coast. The even numbered teams are in Virginia Beach on the east coast.
