On May 18, 2006, Lt. Gen. James R. Helmly, Commanding General, United States Army Reserve Command (USARC), created the United States Army Reserve (USAR) Legal Readiness Command (Provisional) with Brig. Gen. Scott E. Castle assuming command.

In June 2006, the detailed planning for the USAR Legal Readiness Command (Provisional) began in earnest by a small group of Army Reserve Soldiers meeting at the 10th Legal Support Organization (LSO) headquarters in Upper Marlboro, Md.

In January 2007, the Judge Advocate General’s Corps included the USAR Legal Readiness Command (Provisional) in its strategic plan.

On April 13, 2007, Brig. Gen. Jack F. Nevin assumed command of the USAR Legal Readiness Command (Provisional). 

On June 7, 2008, Brig. Gen. Christopher T. Cline assumed command of the USAR Legal Readiness Command (Provisional), and the command’s headquarters moved to Gaithersburg, Md.

On August 7, 2008, USARC formally extended the provisional command and dropped the term “Readiness” from the command’s name.

In September 2008, USARC authorized the USAR Legal Command (Provisional) to exercise command and control over 23 LSOs.

On June 4, 2009, USARC officially organized the USAR Legal Command, putting the command into carrier status.

On September 16, 2009, Brig. Gen. Gill P. Beck assumed command of the USAR Legal Command.

On October 1, 2009, the USAR Legal Command was formally organized and assigned to the USAR Joint and Special Troops Support Command, located in Salt Lake City, Utah.

On November 4, 2011, Brig. Gen. Patrick J. Reinert assumed command of the USAR Legal Command.

On September 16, 2012, the 23 LSOs and five new organizations were designated as Legal Operations Detachments (LOD).

On February 1, 2013, the USAR Legal Command became a direct reporting command to USARC.

Between May 2013 and April 2019, Brig. Gen. LeAnne P. Burch (May 5, 2013), Brig. Gen. Mitchell R. Chitwood (May 16, 2016), and Brig. Gen. Ural D. Glanville (December 1, 2017) assumed command of the USAR Legal Command.

On April 24, 2019, Brig. Gen. Marilyn S. Chiafullo assumed command of the USAR Legal Command where she enhanced AC/RC integration by transforming the historic legal on-site trainings into Total Force Readiness Exercises (TFRX) in support of the Army’s mission. She also successfully maintained command readiness during the COVID-19 pandemic.

On March 26, 2021, Brig. Gen. William B. Dyer III assumed command of the USAR Legal Command, where he instituted METL training, enhancing Legal Command’s overall readiness in line with USARC’s overall training and readiness priorities. He also significantly reduced administrative burdens, thereby freeing up Soldier’s time to focus on missions, which led the way to USARC following suit with similar initiatives.

The USAR Legal Command currently has mission command over 1,500 personnel stationed in 104 cities in 43 states in the continental United States and in two Outside the Continental U.S. (OCONUS) locations.

The USAR Legal Command remains ready and capable in its world-wide mission.
