US Military Spotlight

Value of Service

The U.S. military is an avenue for service. Since the beginning of the republic, millions of service members have raised their hands and sworn to “uphold and defend the Constitution of the United States from all enemies foreign and domestic.”

Our force — the finest in the world and made up entirely of volunteers — delivers across the battlespace. It reinforces American ideals of personal liberty and freedom. And it offers Americans who have the desire and ability to serve training, career mobility and financial benefits in addition to community, connection and a common purpose.

The Defense Department is committed to working with allies, partners and like-minded nations in the Indo-Pacific and to upholding a free and open region founded on respect for international rules, laws and norms.

The United States is working with allies and partners to support Ukraine in the fight for sovereignty and freedom. The U.S. has provided Ukraine with billions of dollars in security assistance since the beginning of Russia's unprovoked assault on Feb. 24, 2022.

The National Guard is "Always Ready, Always There," responding to disasters and other events at home, and ensuring the more than 453,000 Army and Air National Guard personnel are accessible, capable and ready to protect the homeland and provide combat ready resources to the Army and Air Force. Guardsmen also play a key role around the globe, partnering with nearly half the world's nations to advance peace and security.

The Army People Strategy is the roadmap the U.S. Army will use to build a twenty-first century talent-based personnel management system, reform essential quality of life programs and build cohesive teams that are ready, professional, diverse and integrated for the Joint Force. The Total Army will acquire, develop, employ and retain the diversity of Soldier and Civilian talent needed to achieve Total Army readiness.
