First Army remains the most highly-trained and professional multi-component collective training integrator in the US Army; uniquely organized with AC and RC certified skilled Trainers at the point of need in support of the Army's Total Force Policy. Scalable and adaptive, First Army exercises unprecedented capacity to partner with Reserve Component leaders to meet their training readiness requirements, shoulder-to-shoulder through planning, preparation and execution during post pre-mobilization and post-mobilization.


First Army operates within a legislative and legal framework established by National Defense Authorization Acts (NDAA), Public Laws, and Title X of the United States Code, delegated by Headquarters, Department of the Army (HQDA) through FORSCOM. These authorities provide the basis of First Army's role to provide training and readiness oversight to reserve component units.
