According to regulations, how long are CMSgts and CMSgt selects allowed to perform duty out of their CAFSC within a given year?

The correct answer is based on the established regulations which specify that Chief Master Sergeants (CMSgts) and those selected for this rank are allowed to perform duty outside of their awarded Career Field Education and Training Plan (CAFSC) for a total of 270 days within a given year. This provision ensures that while these senior leaders have the flexibility to engage in various duties that may benefit their professional development and the organization, it also limits their time away from their primary specialty. This regulation helps maintain the operational integrity of the Air Force while allowing for skill diversification and leadership opportunities, aligning with the overall mission and strategic objectives.
