Capture the Flag is a team-based game popularized by the Boy Scouts of America as a way to prepare boys for conscription during the World Wars. Urban Capture the Flag (UCTF) is a 21st Century detournement of this practice, primarily organized by anarchists in North America as a way to build community, reclaim the streets and public space, develop insurrectionary and protest tactics for affinity groups, produce a counter-spectacle for passersby, and build group morale through risking together. A short essay on the topic, entitled 'Playing For a New World: Urban Capture the Flag and Insurrection' originally published by ROAD Kingston is available in PDF form by clicking here.
