Marine Corps Knowledge Practice

Which of the following was a major development during the Korean War?

1. Development of jet fighters

2. Introduction of laser-guided bombs

3. Flak Jackets, Thermal Boots, and Vertical Envelopment Doctrine

4. Establishment of the Air Force as a separate branch

The correct answer is: Flak Jackets, Thermal Boots, and Vertical Envelopment Doctrine

The development of Flak Jackets, Thermal Boots, and the Vertical Envelopment Doctrine during the Korean War signifies a crucial evolution in military strategy and soldier safety. The Korean War, fought from 1950 to 1953, presented unique challenges that required innovative solutions for troop protection and operational efficiency in a harsh environment. Flak jackets provided vital protection against shrapnel and small arms fire, significantly enhancing the survivability of soldiers on the battlefield. Thermal boots were essential in addressing the severe cold conditions faced by troops, which could lead to frostbite and other cold-weather injuries. Such gear directly impacted soldiers' comfort and operational effectiveness, allowing them to maintain better mobility and readiness in the frigid climate of Korea. Additionally, the Vertical Envelopment Doctrine emphasized the ability to maneuver forces by utilizing helicopters for troop transport and supplies, allowing for rapid deployment in difficult terrain and potentially surprising the enemy. This doctrine helped transform the tactics employed in ground engagements and showcased an evolving approach to air-ground operations. In contrast, while jet fighters gained prominence during this period, they were not a new development since jet aircraft like the F-86 Sabre were already in service before the Korean War. The use of laser-guided bombs was still largely in the developmental stage
