Air-to-air combat is the engagement of combat aircraft in warfare in which primarily fixed-wing aircraft attempt to destroy enemy aircraft using guns, rockets and missiles. The Korean War saw the greatest amount of air-to-air combat since World War II. During the war the United States claimed to have shot down around 700 fighters. After the war the U.S. Air Force reviewed its figures in an investigation code-named Sabre Measure Charlie and downgraded the kill ratio of the North American F-86 Sabre against the Mikoyan-Gurevich MiG-15 by half from 14:1 to 7:1. One of the factors inflating US numbers was that most dogfights took place over enemy-controlled area. The only way to confirm kills was through gun camera photography. USAF pilots were credited with a kill if the gun camera showed their guns striking the enemy aircraft even if no one actually saw it go down. However, Soviet Air Force kill claims were also highly exaggerated, based upon inherent flaws in their film grading procedures. For instance, the S-13 gun camera was not aligned with either the gunsight or either cannons' ballistics. It ran only while the firing buttons were depressed. Film graders commonly included unit commanders and political commisars who would confirm a "kill"—sometimes even if one had not been claimed by a pilot—when the camera's crosshairs touched the target for two movie frames. During the first 16 months of combat Soviet V-VS units claimed 218 F-86s destroyed when only 36 had been lost. This results in a 600 per cent inflation rate in victory credits over actual Sabres destroyed. However, these figures are complicated by the fact that the Americans routinely attributed combat losses to landing accidents and other causes.
