Before which event did members of the U.S. Armed Forces not receive special training for handling Prisoners of War?

The correct answer signifies that prior to the Korean War, there was no established special training protocol specifically for handling Prisoners of War within the U.S. Armed Forces. The Korean War highlighted the need for more specialized training due to the experiences and treatment of prisoners during that conflict, leading to the development of comprehensive guidelines and instruction to prepare military personnel for dealing with POW situations.

During World War II, while there were some considerations for POW treatment, they were not formalized as specific training programs. The conflicts that followed, such as the Vietnam War and Gulf War, built upon the lessons learned and established practices in the Korean War, ensuring that soldiers were adequately equipped to handle the complexities of POW situations.
