the Sabre's six .50 (12.7 mm) caliber machine guns. The American .50 caliber machine guns, while not packing the same punch, carried many more rounds and were aimed with a more accurate radar-ranging gunsight. The U.S. pilots also had the advantage of G-suits, which were used for the first time in this war. Even after the Air Force introduced the advanced F-86, its pilots often struggled against the jets piloted by Soviet pilots, dubbed "honchos". The UN gradually gained air superiority over most of Korea that lasted until the end of the war. It was a decisive factor in helping the UN first advance into the north, and then resist the Chinese invasion of South Korea. After the war, the USAF claimed 792 MiG-15s and 108 additional aircraft shot down by Sabres for the loss of 78 Sabres. Later research reduced the total to 379 victories which is still higher than the 345 losses shown in USSR records. The Soviets claimed about 1,100 air-to-air victories and 335 combat MiG losses at that time. China's official losses were 231 planes shot down in air-to-air combat (mostly MiG-15s) and 168 other losses. The number of losses of the North Korean Air Force was not revealed. It is estimated that it lost about 200 aircraft in the first stage of the war, and another 70 aircraft after Chinese intervention. Soviet claims of 650 victories over the Sabres, and China's claims of another 211 F-86s, are considered to be exaggerated by the USAF. The Korean war was the first time the helicopter was used extensively in a conflict. While helicopters such as the Sikorsky YR-4 were used in World War II, their use was rare, and Jeeps like the Willys MB were the main method of removing an injured soldier. In the Korean war helicopters like the Sikorsky H-19 partially took over in the non combat Medevac area. Indo-Pakistani Wars During the Indo-Pakistani War of 1965, both air forces engaged each other for the first time in full scale combat since independence. Both countries hold contradictory combat loss claims for the war and no neutral sources have verified them. The Pakistani Air Force (PAF) claimed 104 Indian Air Force (IAF) aircraft while losing only 19 in the process. India meanwhile claims they lost 35 aircraft while shooting down 73 Pakistani aircraft. During the war, the numerically larger IAF, was not able to achieve any
