According to 11-202V3, when are US military aircraft required to comply with ICAO procedures?

Military aircraft are required to comply with ICAO (International Civil Aviation Organization) procedures when it is practical and compatible with their mission. This means that while adherence to these international standards and practices is encouraged to ensure safety and interoperability in airspace that is also used by civilian aircraft, there are instances where military operations may necessitate deviations from these procedures due to unique mission requirements, operational security, or tactical considerations.

This allows military aircraft the flexibility to execute their missions effectively while still recognizing the importance of safety within shared airspace. Such compliance promotes cooperation and coordination between military and civilian air traffic, which can be crucial in high-traffic areas. Understanding this balance highlights the operational priorities of military aviation while also acknowledging the overarching framework provided by ICAO for global aviation safety.
