Countries that border the Pacific are taking part in a massive exercise called "Rim of the Pacific" or "RIMPAC." Dozens of ships, hundreds of aircraft, and thousands of people are practicing their warfighting skills in RIMPAC.
Military photographers and videographers have been sending out hundreds of excellent photos and videos from the exercise this year, and here are 19 of the best of what they'd captured:
1. Marines and U.S. allies attacked the beaches of Hawaii in a simulated amphibious assault
2. Once the Marines hit the sand, they flooded out of their vehicles and got to work
3. Marine attack helicopters flew overhead and provided support to the guys on the ground
5. Ashore, infantry Marines prepped for the hard fight to the island's interior
6. At training areas past the sand, the Marines practiced assaulting buildings and bunkers
7. They even went to firing ranges to practice making stuff blow up
8. Out at sea, the Navy got in the action with a large formation of 40 ships that included some surprising participants ...
BTW, if you want to see hundreds of photos of these 40 ships sailing next to each other, just click on this link. Literally hundreds. There are different angles and close-ups on dozens of the ships available.
9. ... like the Coast Guard's USCGC Stratton ...
10. ... and a Chinese hospital ship, the Peace Ark
11. Onboard the Peace Ark, doctors and other medical personnel practiced treating patients and responding to humanitarian crises
12. Another Chinese ship, the multirole frigate Hengshui, fired on targets to display its proficiency
13. Under the waves, a New Zealand dive unit had to locate an 18-foot shipping container and assist in its recovery
14. A Canadian team found and interrogated an underwater wreck during their training
15. Forces from four allied countries land on a "captured" beach on a Royal Australian Navy landing craft
16. Military vehicles laid down beach matting to prevent other vehicles from slipping on the loose sand. The matting can be laid down in combat to allow tanks and other heavy vehicles to assault towards their objectives quickly
17. Royal Australian combat engineers cleared the way inland for allied forces by searching out mines and other simulated explosives
18. Air Force F-22 Raptors and a tanker aircraft assisted with the exercise, allowing the Air Force to improve its interoperability with the U.S. Navy and foreign militaries
19. The Mexican Navy sent small craft to southern California to practice working with U.S. Navy riverine craft, the small boats that patrol rivers and other tight waterways
RIMPAC takes place on most even-numbered years and has been held 25 times since 1971. America's traditional allies in the Pacific usually attend, but some rivals like Russia and China are common guests as well.
