Operational Lessons Learned in the Korean War

Publisher Marketing: More than 60 years since the outbreak of war on the Korean Peninsula, the United States Armed Forces continue to stand by the soldiers, sailors, airmen, and marines of the Republic of Korea in an effort to deter further North Korean aggression. The purpose of this monograph is capture operational lessons learned during the Korean War that should be taken into consideration by operational planners as they prepare for future conflict on the peninsula. Looking at the Korean Peninsula's geography, weather and terrain, and place in the world highlight unique challenges operational planners will face. The strategic context of North Korea's proximity and alliance to China is important to understand and take into consideration during any operation in the region. China considers North Korea as a buffer protecting its region of Manchuria. Encroachment of this border by foreign forces is a threat to Chinese sovereignty. China's continued support of the North Korean regime is essential to their survival and must always frame the operational environment. The Korean Peninsula is subject to weather extremes, such as monsoons and harsh winters that have a direct impact on operations. During the winter of 1950-1951, marines and soldiers faced sub-zero temperatures and heavy snowfall that blocked mountain passes and clogged main supply routes. Fifty years later, soldiers and airmen serving in Korea experienced another such harsh winter that limited operations because of heavy snowfall and had an impact their ability to respond to threats from the north. The reason that weather has such an operational impact is because of the restrictive terrain found on the peninsula. The Korean Peninsula is primarily mountainous, with most valleys running north to south, and having limited east west cross mobility corridors. In the north, limited infrastructure, such as road networks and expressways, compounds the problem. Add to this, population centers based around crossroads along the valley floors, and the terrain becomes even more restrictive to ground maneuvers. By examining combat operations during the Korean War, it becomes apparent that operational planners must consider force structure. The allocation of force multipliers to enable independent brigade operations without the possibility of mutually supporting maneuver units is critical in Korea's restrictive terrain. A look at the terrain and weather found on the peninsula, along with a short history of Korea, sets the stage for a look at the Korean War. Following United Nations forces through their first year of fighting through the lens of operational art highlights relevant lessons learned for the operational planner. Couching these lessons learned in the Korean environment of today, establishes a framework that is useful for operational planners.
