Happy Birthday Marine Corps

In an evolving and complex world, we will excel as the Nation’s expeditionary “force of choice.”
— General James T. Conway, 34th Commandant of the Marine Corps Marine Corps Vision and Strategy 2025

Our Motto

Semper Fidelis means Marines are “Always Faithful” to the country, the Marine Corps and each other. Our nation entrusts us with its young men and women and we respond with an unbreakable commitment, in combat and in life.


The Marine Corps has been America’s expeditionary force in readiness since 1775. We are forward deployed to respond swiftly and aggressively in times of crisis. We are soldiers of the sea, providing forces and detachments to naval ships and shore operations. We are global leaders, developing expeditionary doctrine and innovation that set the example, and leading other countries’ forces and agencies in multinational military operations.

These unique capabilities make us “First to Fight,” and our nation’s first line of defense.

Fighting Philosophy

Every Marine is a rifleman, trained first as a disciplined warrior regardless of occupational specialty. This training is key to our philosophy of maneuver warfare. Maneuver warfare combines strategic positioning with firepower, demands agile forces capable of quick decision making, and employs the human elements of war — boldness, creativity, intelligence and the warrior spirit.

Our combined arms approach compounds Marine Corps strength by bringing our land, air and sea forces together to achieve every mission. This organization creates a scalable force with incomparable war-fighting capabilities. It is the key to winning battles.
