U.S. supremacy is increasingly contested in the land, air, maritime, space and cyberspace domains. While the U.S. has been engaged in counter-insurgency operations for the last 15 years, potential adversaries have modernized and studied how we fight, and will seek to threaten our critical capabilities through multiple domains. Multi-Domain Battle is an emerging concept between the Army and Marine Corps, in concert with the Joint Force, to help maintain American military dominance in all five domains - land, air, maritime, space, and cyberspace, and across the electromagnetic spectrum.

"They are fracturing our way of war by using other domains. We can't do it with two domains. Air and land is not enough."

"The U.S. military along with allies and partners will project power across multiple domains to decisively defeat the adversary by compelling it to cease hostilities or render its military incapable of further aggression."

"Employing Multi-Domain Battle, joint forces with integrated cross-domain capabilities provide a credible capability to deter adversary aggression, deny the enemy freedom of action, ensure joint force access, secure terrain, and consolidate gains."
