This is what a joint US Marine-Japanese training exercise looks like
Military planners spend years putting training exercises together and the political ramifications can be steep, such as with the annual Foal Eagle exercise on the Korean Peninsula. North Korea has a history of shelling South Korean islands and firing missiles into the Sea of Japan whenever the U.S. and South Korea come together to train. Calling them "maneuvers" or "war games" is an oversimplification. The long-term consequences could be life or death.

There are times the U.S. will even conduct joint training operations with rivals and allies, such as the annual Cobra Gold exercise in Thailand, where Chinese forces were allowed to join in the humanitarian part.

2o16 marked the tenth year of Iron Fist, an exercise where soldiers of the Japanese Ground Self-Defense Force trained with U.S. Marines from the 11th Marine Expeditionary Unit (MEU) to refine their amphibious landing abilities. The 11th MEU trained with the Japanese for five weeks at Camp Pendleton and Twentynine Palms, California. Their focus was on small unit combat and amphibious landings.
