Operation Ironclad
Disciplined Units Are Hard To Kill

OPERATION IRONCLAD is a deliberate effort to suppress complacency and strengthen discipline across the largest MAGTF in the Marine Corps, ensuring readiness for competition and conflict with a near-peer adversary. By reinforcing core competencies, holding leaders accountable, and demanding the highest standards, the operation aims to build a more precise, professional, and combat-ready force. This is not a return to tradition, but a necessary sharpening of the force to meet the demands of an increasingly complex and contested battlespace.
