Description

Expeditionary Warfare School is a subsidiary of USMC that focuses on the teaching and mastery of Marine Corps doctrine, tactics, and history. EWS is a two-phased program that challenges students to think critically as leaders by providing them with a firm doctrinal foundation, augmented with the exchange of practical experiences, and reinforced with extensive practical application and planning exercises. While there are seldom “correct,” or “incorrect,” answers on the battlefield, there are certainly educated and uneducated perspectives. The onus is on the student to invest the intellectual humility, curiosity, and time in bringing an informed perspective to the Marines under their command.
