Korea War Operation Chromite Operational Environment

The Pusan Perimeter War was a wide scale battle between North Korean and United Nations forces in the 1950. While this was the first major involvement of the Korean War, the UN forces involved in the battle comprised forces from the United States, the United Kingdom, and Republic of Korea. The current operational environment during this battle included the advancement of North Korea forces around the Pusan Perimeter in order to encircle it from every side. These forces advanced following their conquest of Taejon and moved towards United Nations' positions, which pushed back American and South Korean forces. Apart from the advancement of the North Korean forces, there are other factors that contributed to the dire situation facing the U.S. Eighth Army at the Pusan Perimeter. One of these conditions was steady decrease since the end of the Second World War. Secondly, the Army was in dire situation because it was under strength and had old-fashioned equipment. Third, the U.S. Eighth Army faced logistic difficulties and terrain as well as increased pace of air interdiction. These forces were manned by young men without combat seasoning, adequate training, and necessary heavy weapons.

During the battle, NKPA faced pressures emerging from the cost of advancing amidst heavy and effective air attacks by the United Nations' troops. General MacArthur's vision for Operation Chromite relieved NKPA pressure on the U.S. Eighth Army in the Pusan Perimeter. The vision relieved NKPA on the American Army by enabling the inclusion of new units into the battle as they became available. In essence, General MacArthur's vision achieved this goal through helping to ensure that NKPA pressure was a responsibility of all UN troops rather than a responsibility of the U.S. Eighth Army alone.

2. Strategic Guidance

General MacArthur's vision for the operational environment upon the completion of Operation Chromite included an end state or desired end, which was the main focus of the war. His vision for the operational environment upon completion was to capture Inchon and enable the United Nations to recapture Seoul. In this case, the general envisioned that the end state of the battle would be characterized by U.S. Eighth Army's control of Inchon and control of Seoul by the United Nations. General MacArthur's vision included a four point strategy that would help in achieving this end state or desired state of the operational environment after completion of the battle. The realization of the end state would entail striking at the rear of North Korean forces, hindering supply lines to the south, threatening Pyongyang, North Korean capital, and obtaining political advantage through recapturing Seoul. Actually, Operation Chromite mainly focused on taking control of Inchon and eventual control of the region through an amphibious assault involving various forces. The eventual control of Inchon and Seoul was the desired end state of the operational environment.

As previously mentioned, the achievement of General MacArthur's end state of the operational environment involved the use of various forces with different roles such as JTF 7 and X Corps. The role of X Corps in realization of this end state was to carry out a phased amphibious landing at Inchon before advancing inland to recapture Seoul. During this process, X Corps would disconnect the enemy's main communications lines and resupply to forces focusing on the south. In contrast, the Joint Task Force (JTF) 7 was established following the recognition of the increased complexity of amphibious operations at Inchon. The role of JTF 7 was to help in the finalization and executions of the landings through providing necessary support that would help in securing the Inchon area.

3. Decisive Points

Similar to other operations, the success of Operation Chromite was dependent on decisive points that created a desired impact or promoted the realization of a specific objective. A decisive point is basically defined as a certain major event, geographic location, function, or crucial factor that enables a commander to gain advantage over an enemy when acted upon. One of the decisive points for Operation Chromite was the use of asymmetric action, which involved UN sea and air combat power against NKPA ground forces. The impact of this decisive point in the achievement of a specific objective is evident in the fact that it enabled the commander to stabilize the situation and identify a means of exploiting the potential of his forces. This was achieved through application of joint force strength and capabilities against the weaknesses of the NKPA throughout the whole battlefield. Actually, the ability to operate in the air and at sea was a critical success factor for General MacArthur's forces that NKPA forces did not have.

Since the beginning, the commander understood the need to conduct decisive joint offensive operations in order to obtain victory. An understanding of the goals of the operation and creation of effective strategies was brought by MacArthur's assessment of the situation upon arrival in Korea and development of plans to capitalize on the strengths and advantages of launching an amphibious landing in the adversary's territory. The commander effectively envisioned how his forces would engage in the battle and started to plan for the future from the day he arrived in order to stabilize the situation. Apart from situational assessment, MacArthur also understood the strengths and weaknesses of his forces and capitalized on the strengths to achieve the operation's objectives.
4. Operational Maneuver

Operational maneuver is described as the use of forces in the operational area via movement in combination with fires in order to gain a position of advantage over the enemy. For Operation Chromite, operational maneuver involved the breakout of the Eighth Army at the Pusan Perimeter in order to reverse the situation and obtain advantage over NKPA. The reversal of the situation at the Pusan Perimeter by the U.S. Eighth Army involved the use of air interdiction on NKPA. Air interdiction was used against NKPA at the Pusan Perimeter battle since it provided an advantageous position for MacArthur's forces and contributed to significant logistic challenges for NKPA. Given the inadequacy of air interdiction to effectively deal with NKPA, the reversal of the situation at the Pusan Perimeter entailed the infusion of fresh manpower given the dire situation of the U.S. Eighth Army. The commander added units into the battle as they became available because of the continued threat by the enemy. These factors were part of amphibious operation that enabled Allied forces to change the situation at the Pusan perimeter.

The other aspect of operation maneuver was tactics used to place the Allied forces in an advantageous position over the NKPA. In this case, the Allied forces used an amphibious operation that was characterized by a combination of air and sea attacks. During this process, the Allied forces attacked the enemy's strategic targets in order to prevent them from moving reinforcements by land. In order to gain strategic advantage and position over NKPA, Allied forces in the amphibious operation drove inland to recapture Seoul while cutting NKPA's main communications lines and ensuring resupply of forces in the south. Despite the difficulties in putting the forces together in order to make the landing, the advancements and disconnection of the enemy's communications lines enabled Allied forces to obtain strategic position over NKPA.

5. Joint Fires

The application of fires can help in generating the desired effects to gain the objective of an operation. For Operation Chromite, joint fires would provide support for the battle through various aspects including landing forces at Inchon. Joint fire support for landing forces at Inchon would help in gaining a strategic advantage over NKPA by preventing any retaliatory attacks that could interfere with the operations. In this case, joint fire would enhance the capabilities of forces landing at Inchon and generate further logistical challenges for NKPA that was already experiencing difficulties associated with increased air interdiction. Moreover, joint fire support for landing forces at Inchon would help interdict the strategies and tactics of the enemy, which would further weaken NKPA.

Joint fire support for attacking the NKPA's lines of communications would help in promoting the advancement of Allied forces towards recapturing Seoul. In this case, the Allied forces will complicate the logistical issues facing NKPA by ensuring their communications are not effective and preventing their increased advancement into the Allied forces positions. While attacking NKPA's lines of communications, joint fire support for this process would promote increased heavy and effective attacks on the enemy by Allied forces. In addition, joint fire support for this operation would promote easy advancement of the Allied forces into NKPA's positions and result in the eventual seize of Inchon and Seoul.

Joint fire support for interdicting any NKPA efforts to counterattack or reinforce forces vicinity Inchon and Seoul would entail the infusion of fresh manpower into strategic positions in these regions. The Allied forces would deploy more troops into these region's strategic positions and preempt and prevent any retaliatory attacks rather than wait for the attacks to…
