The Battle of the Bulge (16 December 1944 – 25 January 1945) was the last major German offensive campaign on the Western Front during World War II.
 It was launched through the densely forested Ardennes region of Wallonia in eastern Belgium, northeast France, and Luxembourg, towards the end of World War II.
 The surprise attack caught the Allied forces completely off guard.
 American forces bore the brunt of the attack and incurred their highest casualties of any operation during the war.
 The battle also severely depleted Germany's armored forces, and they were largely unable to replace them.
 German personnel and, later, Luftwaffe aircraft (in the concluding stages of the engagement) also sustained heavy losses.
The Battle of Chipyong-ni (French: "Bataille de Chipyong-ni" ), also known as the Battle of Dipingli (), was a decisive battle of the Korean War, that took place from 13–15 February 1951 between American and French units of the US 23rd Infantry Regiment and various units of the Chinese People's Volunteer Army (PVA) around the village of Chipyong-ni, present-day Jipyeong-ri.
 The result was a United Nations Command victory.
 The battle, along with the Third Battle of Wonju, has been called "the Gettysburg of the Korean War," and represents the "high-water mark" of the Chinese incursion into Korea.
 Due to the ferocity of the Chinese attack and the heroism of the defenders, the battle has also been called, "...one of the greatest regimental defense actions in military history."
The Second Battle of Naktong Bulge was an engagement between United Nations (UN) and North Korean (NK) forces early in the Korean War from September 1 to September 15, 1950, along the Naktong River in South Korea.
 It was a part of the Battle of Pusan Perimeter, and was one of several large engagements fought simultaneously.
 The battle ended in a victory for the United Nations after large numbers of United States (US) and Republic of Korea (ROK) troops repelled a strong North Korean attack.
The Battle for Outpost Vegas was a battle during the Korean War between the armed forces of the United States and China from March 26–28, 1953, four months before the end of the Korean War.
 Vegas was one of three outposts called the Nevada Cities north of the Main Line of Resistance (MLR), the United Nations defensive line which stretched roughly around the latitude 38th Parallel.
 Vegas, and the outposts it supported, Reno and Carson, were manned by elements of the 1st Marine Division.
 On March 26, 1953 the Chinese army launched an attack on the Nevada Cities, including Vegas, in an attempt to better the position of China and North Korea in the Panmunjon peace talks which were occurring at the time, and to gain more territory for North Korea when its borders would be solidified.
 The battle raged for five days until Chinese forces halted their advance after partially obtaining their objective through capturing one outpost north of the MLR on March 28.
 The battle for outpost Vegas and the surrounding outposts are considered the bloodiest fighting to date in western Korea during the Korean War.
 It is estimated that there were over 1,000 American casualties and twice that number of Chinese during the Battle for Outpost Vegas.
 The battle is also known for the involvement of Sergeant Reckless, a horse in a USMC recoilless rifle platoon who transported ammunition and the wounded during the U.S. defense of outpost Vegas.
The First Battle of Naktong Bulge was an engagement between United States and North Korean forces early in the Korean War from August 5–19, 1950 in the vicinity of Yongsan (Yeongsan, Changnyeong county) and the Naktong River in South Korea.
 It was a part of the Battle of Pusan Perimeter, and was one of several large engagements fought simultaneously.
 The battle ended in a victory for the United States after large numbers of US reinforcements destroyed an attacking North Korean division.
Nakdong River Battle Museum is a small museum built inside the Apsan Park to commemorate the soldiers and civilians killed during the Korean War at a battle that raged near the Nakdong River.
 The grounds around the museum are scattered with vintage tanks and airplanes from the Korean War.
 Built in 1979 the museum has two floors with exhibits from the Korean War and other significant eras in Korea's past.
 Other areas within the museum pay tribute to those that died in both natural and man-made disasters in Korea's past.
Kang Kon (Chosŏn'gŭl: 강건 ; June 23, 1918 - September 8, 1950) was a Korean military leader active in Manchuria and the Korean peninsula during the years leading up to the Korean War and during the first stages of the Korean War in 1950.
 Kang (born Kang Shin-tae) was born in Sangju, Gyeongsangbuk-do, on June 23, 1918, and at the young age of 16 began his involvement in liberation and military ventures.
 As a teenager, he was actively involved in recruiting anti-Japanese guerrillas for his long-time friend, Kim Il Sung, and is remembered as being unusually tall and often towering over others.
 Before his leadership roles in the Korean War, Kang joined the anti-Japanese struggle in Manchuria in 1932, and later fled into Soviet territory in the early 1940s, where, by the end of World War II was an officer in the 88th Independent Brigade in the Red Army, consisting of both Korean and Chinese soldiers.
 Lieutenant General Kang led the North Korean Army offensive during the opening stages of the Korean War until he was killed by a land mine on September 8, 1950.
The Korean War (in South Korean Hangul: 한국전쟁 ; Hanja: 韓國戰爭 ; RR: "Hanguk Jeonjaeng " , "Korean War"; in North Korean Chosŏn'gŭl: 조국해방전쟁 ; Hancha: 祖國解放戰爭 ; MR: "Choguk haebang chǒnjaeng " , "Fatherland Liberation War"; 25 June 1950 – 27 July 1953) was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the principal support of the United States).
 The war began on 25 June 1950 when North Korea invaded South Korea.
 The United Nations, with the United States as the principal force, came to the aid of South Korea.
 China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North.
The Battle of Unsan (Hangul: 운산전투 ; Hanja: 雲山戰鬪 ; RR: "Unsan jeontu "; MR: "Unsan chŏnt'u " ), also known as the Battle of Yunshan (), was a series of engagements of the Korean War that took place from 25 October to 4 November 1950 near Unsan, North Pyongan province in present-day North Korea.
 As part of the Chinese First Phase Campaign, the People's Republic of China's People's Volunteer Army made repeated attacks against the Republic of Korea 1st Infantry Division near Unsan beginning on 25 October, in an attempt to take advancing United Nations forces by surprise.
 In an accidental first encounter with the United States military during the Korean War, the Chinese 39th Corps attacked the unprepared US 8th Cavalry Regiment in Unsan on 1 November, resulting in one of the most devastating US losses of the Korean War.
The Battle of Hoengsong was a battle during the Korean War.
 It took place between 11–15 February 1951.
 As part of the renewed Chinese assault on the UN strongholds in Korea, it was the first part of the CPVA Fourth Phase Offensive, and was fought between the Chinese and United Nations forces.
 The Chinese were victorious in this battle, having inflicted heavy casualties to the UNC forces in the two days of fighting.
 South Korean soldiers were ordered to lead the assault and the U.S. were ordered to support them, not lead the assault this time.
 Unfortunately, after the Chinese offensive began, retreating South Korean soldiers streamed south past U.S. support forces, allowing the Chinese to flank American positions.
 Soon, the Chinese owned the narrow, twisting valley north of Hoengsong and the road that ran through it, the only escape route.
 Hundreds of U.S. soldiers including field artillerymen, infantry, and logistics soldiers were killed by Chinese forces, resulting in one of the most lopsided defeats suffered by the U.S. military in the Korean War.
