The chances of dying skyrocketed for participants of the Korean War's famous battles. Of the 30,000 U.S. troops in the Battle of the Chosin Reservoir, for example, just under 6,000 were killed or went missing, a 19.75% loss.
As of November 2019, there are now 33,739 reported combat deaths in theater, 2,835 non-combat deaths in theater and another 17,672 non-combat deaths outside the Korean War. If the Korean War had lasted as long as the Vietnam War, the death toll would have climbed to 168,630 -- more than World War I.
The success of American battlefield medicine and operational risk management continues through the wars in Iraq and Afghanistan. According to the most- current analysis of casualties from the wars in Iraq and Afghanistan, updated May 2020, 2.5 million American troops deployed in support of Operations Enduring Freedom, Iraqi Freedom and New Dawn. Of those, 5,364 died in action, and another 1,476 died in non-hostile incidents.
