Army leaders have introduced a multi-domain battle concept, which will allow the Army to stretch its capabilities not only to land but also to air, sea, space and cyberspace domains. A key concept of multi-domain battle is "demand reduction," meaning reducing the need to supply the brigade combat team with fuel, ammunition, water, energy and other supplies through technological innovations.
