World War II combatives are Close Quarter Combat techniques, including hand-to-hand and weapons techniques (bayonet/knife) that were taught to allied special forces in World War II by such famous instructors as Rex Applegate and William Ewart Fairbairn.

Some instructors teach or incorporate techniques based on these combatives still today in the Britain, Canadian and the United States. Some examples are:

• American Combatives (ACI)
• Bill Underwood's Combato and Defendo, taught by Robert Cressman and others
• Canadian Combato
• Jim Grover's Combatives
• Rocky Mountain Combat Training Applications (RMCAT)
• Ted Truscott's Close Quarter Combat based on the FAS system (hand to hand combat designed for the British Home Guard during WWII)
