Step-by-step explanation:
The Expeditionary Sustainment Commands (ESC) are specialized units within the United States Army that are responsible for providing logistical support to combat units. This includes tasks such as transportation, maintenance, supply, and services required to sustain military forces during expeditionary operations. The ESC is a critical component for the Army's ability to project and maintain a force in remote and hostile areas.
These commands are made to be rapidly deployable and are designed to support operations ranging from major combat operations to humanitarian assistance and disaster relief. The utilization of an ESC allows for a more focused and efficient management of resources, ensuring that combat units receive the necessary support to maintain their operational effectiveness.
