The united states employs its military capabilities at home and abroad in support of its national security goals in a variety of operations known in doctrine today as

Range of Military Operations in planning.

These operations vary in size, purpose, and combat intensity within a range of military operations that extends from military engagement, security cooperation, and deterrence activities to crisis response and limited contingency operations, and, if necessary, to major operations and campaigns. The use of joint capabilities in military engagement, security cooperation, and deterrence activities shapes the operational environment and helps to keep the day-to-day tensions between nations or groups below the threshold of armed conflict, while maintaining US global influence.
