Step-by-step explanation:
Once a Sailor's readiness waiver expires and they still have 3 or more Physical Fitness Assessment (PFA) failures, certain actions need to be taken. In the U.S. Navy, failure to meet the PFA standards can result in consequences like non-promotion, early separation, or even discharge from service. The specific steps that need to occur when a Sailor has multiple PFA failures after their readiness waiver expires depend on various factors, such as the Sailor's overall performance, individual circumstances, and command discretion.
