What is the primary focus of Phase I TBS?

Phase I of The Basic School (TBS) primarily emphasizes the development of individual skills that are foundational for every Marine officer. This phase is designed to ensure that each officer possesses the essential competencies required for leadership and operational effectiveness. These skills encompass a wide range of areas, including physical fitness, marksmanship, land navigation, patrolling, and administrative duties, which are critical not only for personal proficiency but also for leading and training others in subsequent phases.

The focus on individual skills sets the groundwork for future leadership roles within a rifle squad or platoon, which are explored more comprehensively in later training phases. Although leadership of a rifle squad or platoon is crucial, the foundational individual skills learned in Phase I equip officers with the necessary tools to excel in these responsibilities as they progress.

Therefore, this emphasis on personal skill development in Phase I is vital as it directly influences an officer's readiness to operate effectively within a team and the broader Marine Corps structure.
