Army commands are organizational structures within a military that oversee specific operations, units, or regions. Each command is responsible for various aspects of military readiness, training, and deployment. They ensure that troops are prepared for missions and that resources are allocated effectively. In the United States, for example, there are several major commands, such as U.S. Army Forces Command and U.S. Army Central. These commands coordinate activities across different units and support the overall strategic goals of the Department of Defense. Each command plays a crucial role in maintaining national security and responding to global challenges.
