Spiritual fitness is foundational to warfighting. To maintain a high level of morale & efficiency in combat, small-unit leaders must understand how to exercise and maintain there own spiritual fitness while leading Marines and Sailors to do the same. #NoMarineFightsAlone

Resiliency is forged in the fire. It’s the decision to take one more step when everything in you wants to stop. It’s adapting when the plan falls apart and knowing the Marine beside you will do the same. We don’t break. We don’t quit. We don’t stop fighting. #NoMarineFightsAlone
