What do Major Commands (MAJCOMs) establish?

Major Commands (MAJCOMs) within the Air Force and other military branches are primarily responsible for overseeing specific areas of operations and mission sets. One of their key functions is to establish supplemental instructions that cater to the distinct needs of their operations. These instructions are designed to provide detailed guidance and reinforce compliance with overarching directives while addressing the unique aspects of the MAJCOM's focus area.

By creating supplemental instructions, MAJCOMs ensure that their subordinate units can operate effectively within the context of their specific missions, taking into account unique operational conditions, equipment, and organizational requirements. This level of customization allows them to maintain operational readiness and enforce standards that may not be fully covered by broader directives from higher command levels.

In contrast, while other options like global health initiatives or emergency evacuation plans could be part of a MAJCOM's responsibilities, they are typically broader initiatives that involve coordination across multiple levels and agencies rather than the specific instructional guidance tailored to unique operational requirements.
