Common Skills Training (CST) is designed to equip all Marines with essential skills that are broadly applicable, regardless of their specific military occupational specialty (MOS). This foundational training ensures that every Marine has a baseline level of proficiency in critical areas that are vital for operational effectiveness and readiness. CST includes training in areas such as physical fitness, basic first aid, combat skills, and other competencies necessary for mission success in varied environments.

This training is integral to maintaining a cohesive and capable force, as it allows Marines from diverse backgrounds and specialties to work effectively together. In contrast, advanced leadership training, in-depth technical skills, and specialized language training target more specific needs that do not apply universally to all Marines. Therefore, the focus of CST on essential skills for every Marine reinforces the core values and operational readiness of the Marine Corps as a whole.
