Which of the following is true regarding military flight operations?

Military flight operations indeed often include abrupt flight maneuvers. This is necessary for a variety of reasons, including training for combat scenarios, pilot proficiency, and the execution of tactical missions. Military pilots are trained to perform complex maneuvers that can involve high angles of attack, rapid climbs, sharp turns, and other operations that are typically not practiced in civilian aviation due to safety regulations and operational limitations.

The other choices presented do not accurately reflect the characteristics of military flight operations. While it is true that some operations may occur above 10,000 feet, many military flying activities also take place at lower altitudes, particularly for training and operational purposes. Military flight operations are not restricted to non-combat training; they include a wide range of missions such as logistics, air support, reconnaissance, and actual combat. Lastly, military operations involve various types of aircraft, including fixed-wing planes, drones, and helicopters, and are not limited to just helicopters. The diversity in aircraft types allows militaries to effectively accomplish different kinds of missions based on specific operational needs.
