What items were first used by Marines during the Korean War?

The use of helicopters and flak jackets by Marines during the Korean War represents a significant evolution in military tactics and personnel protection. Helicopters allowed for rapid troop transport, medical evacuations, and logistical support in difficult terrain, which was especially vital during the fluid and mobile warfare seen in Korea. The introduction of the helicopter profoundly changed how ground operations could be conducted, enabling Marines to respond quickly to various combat scenarios.

Flak jackets provided essential protection against shrapnel and small arms fire, enhancing soldiers' survivability on the battlefield. This was particularly crucial in the Korean War, which saw intense combat and a need for better personal protection for troops in close-range fighting. Together, the implementation of helicopters and flak jackets marked a paradigm shift in operational capability and soldier defense, highlighting the innovation and adaptation of the Marine Corps in the face of new challenges.
