[QUOTE]During WWI Bill Underwood created his own unique system of close quarter combat known as "Combato". During WWII he was commissioned to provide instruction to Canadian, American and British Special forces and to secret agents at Allies Top Secret training school, Camp-X. In 1945, after the war, Bill modified his system for the civilian world, law enforcement and security sectors. He renamed his system "Defendo" putting a greater focus on non-lethal techniques and highly practical, effective self-defense. Defendo International Ltd. is the only organization in the world preserving and teaching the genius of Bill Underwood's Defendo and Combato in their original forms.[/QUOTE]
