In which phase of training do drill sergeants reduce supervision and reinforce skills?

The phase of training where drill sergeants reduce supervision and reinforce skills is the Black Phase, also known as Phase 4. During this phase, trainees are expected to solidify the competencies and knowledge they have learned in previous phases. This is a critical transition point where the level of oversight from drill sergeants is decreased, allowing trainees to gain more independence and responsibility in applying their training.

The focus during the Black Phase is on refining essential skills and preparing trainees for future challenges, which necessitates a shift in how drill sergeants interact with them. By fostering a more self-reliant environment, trainees are encouraged to demonstrate their proficiency and readiness to operate with less direct supervision. This phase is crucial in building confidence and reinforcing the foundational skills that will carry them forward as they prepare for their military careers.
