The Role of the U.S. Constitution and the Armed Forces

The Role of the U.S. Constitution and the Armed Forces


By Ronald C. Johnson, Ph.D.

Faculty Member Management at American Public University

The role of the Constitution of the United States parallels closely the genesis of the Armed Forces. General George Washington, who went on to become our nation’s first President, was a proponent of a life of military service; he and the other founders ensured the Constitution reflected the principles of military service.

Article 1, Section 8 of the Constitution provides Congress authority to raise and support Armies and to provide and maintain a Navy.  The U.S. Constitution continues to shape the conduct of the branches of the armed forces. This can be seen today through the lens of the oath of office taken by service members when they join the military.

The Oath of Office

The first oath of office took place June 1, 1789. There are two oaths: one for officers and the other for enlisted personnel. Keskel (2002) tallies 19 legislative actions affecting the oath: 11 for the officer oath, three that address the enlisted oath, and five that address both.

The current officer oath of office has been unchanged since July 11, 1868 and the enlisted oath is unchanged since October 5, 1962. It really is amazing how resilient this oath has been and how little it has changed since its inception.

US Military Core Values and the Oath of Office

The tenets of the oath of office are well-matched with the core values of our armed forces. Keskel (2002) provides information on how the oath of office supports the core values of each branch the armed forces. The opening phrase, I will support and defend the Constitution of the United States against all enemies, foreign and domestic relates to the Air Force core value “service before self”; the Navy and Marine Corps core value “courage”; and the Army’s “selfless service, personal courage and loyalty.”

This sets the stage for what is to follow: I will bear true faith and allegiance to the same. This correlates with the core values of honor and integrity in all we do. I take this obligation freely, without any mental reservation or purpose of evasion, is similar to the Air Force core value of “integrity first,” “honor” for the Navy and Marines, and “integrity” for the Army.

The concluding phrase I will well and faithfully discharge the duties of the office upon which I am about to enter conveys support for the Air Force core value of “excellence in all we do”; Navy and Marine Corps “commitment”; and the Army core value of duty and respect (p. 9).

What Today’s Troops Have to Say

One of the privileges of being a professor at APUS is the daily interactions in the classroom with military students. I live and work near Ramstein Air Base in Germany, which has the largest concentration of Americans living overseas.

Recently, I was in an on-base café with a group of 15 Marines, airmen, and soldiers on their way home from a tour of duty in Afghanistan. After we chatted for a while and I thanked them for their service, the discussion turned to Constitution Day and the oath of office.

Each member of the unit remembered clearly the first time they came in contact with the oath of office. Some recalled it as an awesome experience they will never forget. A Marine stated that he “felt like I was becoming part of something much bigger than me.” Finally, an airman could only remember that his hand was shaking while reciting the oath.

Discussion turned to how the core values of each of the services came into play with their duty. One senior service member said that it represented, “committing myself to a lifestyle where lawful orders can get me through dangerous duty.”

Another declared how leaders set the example, both good and bad – and that establishing trust is important when considering core values. A Marine agreed: “Nice words and bumper stickers do not mean a thing without leaders leading in an exemplary manner.”

Others said the oath is a good framework for guiding behavior, as well as a gateway to the core values. In the words of a young enlisted Marine, “In a combat zone we are thinking about why we are there and our core values keep us grounded.”

This discussion made me feel proud of the service members who have served, both yesterday and today. It made me proud that we live in a country where a document such as the United States Constitution can still be relevant after all these years.


The U.S. Constitution and the U.S. Armed Forces have quite a shared history – one that is still going strong and one that bodes well for the future.
