Combatives is the United States Army's term for hand-to-hand combat training and techniques.

Militaries have long taught unarmed combat, both as physical conditioning, and as a supplement to armed combat. Among the samurai of Japan, such combatives were known as Bujutsu (jujutsu, tantojutsu, bōjutsu and so on). Like weapon arts such as kenjutsu, yarijutsu and naginatajutsu, these often were adapted in later stages to cultural or sport forms such as kyūdō, judo, or kendo. Though technology changed with the emergence of gunpowder, the machine gun in the Russo-Japanese War, and the trench warfare of World War I, hand-to-hand fighting methods such as bayonet remained central to modern military training.

Sometimes called Close Quarters Combat (CQC or close combat), World War II-era American combatives were largely codified by Britons William E. Fairbairn and Eric A. Sykes. Also known for their eponymous Fairbairn-Sykes Fighting Knife, Fairbairn and Sykes had worked in the British Armed Forces and helped teach the Shanghai Municipal Police (SMP) quick, effective, and simple techniques for fighting with or without weapons in melee situations. Similar training was provided to British Commandos, the First Special Service Force, Office of Strategic Services, Army Rangers, and Marine Raiders. Fairbairn at one point called this system Defendu and published on it, as did their American colleague Rex Applegate. Fairbairn often referred to the technique as "gutter fighting," a term which Applegate used, along with "the Fairbairn system."
