This Big Picture film on Special Forces Amphibious Training in 1956 Okinawa is insightful.
Of note is the fact that the “fighting frogman” detachment receives instruction in conducting water insertion and demolition training off the coast of White Beach aboard a U.S. Naval ship while wearing their floppy Lovat Scouts-style green berets– which was not officially approved for wear by the Army until 25 September 1961 in an evolved, more close-fitting, format.
The tactics covered are classic late WWII/Korean War-era UDT team and Marine recon evolutions. Good stuff regardless.
Those triple tank rigs, tho…
Thanks, Jeff!
