US Navy/Mass Comm. Specialist 1st Class Daniel Hinton
Multinational special operations forces participate in a submarine insertion exercise with the fast-attack submarine USS Hawaii and combat rubber raiding craft off the coast of Oahu, Hawaii, July 9, 2018.
On July 12, US soldiers and sailors and foreign counterparts blew up a retired US warship roughly 60 miles north of Hawaii, bludgeoning the decommissioned USS Racine with missiles and torpedoes as a part of the Rim of the Pacific exercise, a series of drills attended by 25,000 personnel from 25 countries around the Pacific between June 27 and August 2.
A few days before, the fast-attack submarine USS Hawaii carried out a much more discreet mission closer to the shores of Oahu, secreting special-operations personnel close to shore to practice a submarine-insertion maneuver that's a mainstay of naval commando raids.
Below, you can see how US special operations force troops and their counterparts from six other countries carried out a submarine-insertion exercise.
