From the Document: "Congress has expressed concern about the growing threat to U.S. national security posed by a resurgent Russia and China. The Army contends in order to address the threat, it must be able to operate in a multi-domain (air, land, water, space, cyber, information) environment, which requires new operational concepts, technologies, weapons, and units. The Multi-Domain Task Force (MDTF) is the Army's self-described 'organizational centerpiece' of this effort."
