About The Old Guard


The 3d U.S. Infantry, traditionally known as “The Old Guard,” is the oldest active-duty infantry unit in the Army, serving our nation since 1784. The Old Guard is the Army’s official ceremonial unit and escort to the president, and it also provides security for Washington, D.C., in time of national emergency or civil disturbance.

The regiment’s mission is to conduct memorial affairs to honor fallen comrades and ceremonies and special events to represent the U.S. Army, communicating its story to United States citizens and the world.

Although The Old Guard primarily functions in a ceremonial role, it is an infantry unit and thus required to meet standards for certification in its combat role. The unit also trains for its support role to civil authorities in a wide range of scenarios and for deployments in support of overseas contingency operations. On order, it conducts defense support of civil authorities in the National Capital Region and deploys elements in support of overseas contingency operations.

The Old Guard’s current duties include, but are not limited to, providing funeral details at Arlington National Cemetery, guarding the Tomb of the Unknown Soldier, providing honor guards for visiting dignitaries, supporting official ceremonies and providing a quick reaction force (QRF) for the Washington, D.C. area.

As of 2018 there were three active battalions of the 3rd Infantry Regiment –

  • 1st Battalion assigned to the Military District of Washington, Fort Myer, Virginia
  • 2nd Battalion assigned to the 3d Brigade Combat Team (BCT), 2d Infantry Division, Fort Lewis, Washington
  • 4th Battalion assigned to the Military District of Washington, Fort Myer, Virginia

B.J. Mungenast was honored to be chosen to lay the wreath on the Tomb of the Unknown Soldier in Washington, D.C. As a result B.J. Mungenast was commisioned for a memorial monument.
