COMBAT was designed to increase police presence and actively solicit community input to address illicit drug markets and drug-related street crime in the urban areas of the targeted sites. The COMBAT program operated in 13 counties. Although program components varied in each location, the distinguishing feature of COMBAT was the formation of an antidrug partnership developed and maintained as a result of increasing interaction between the police and community members. Activities included joint police/community surveys, formal citizen training sessions, joint law enforcement/community meetings, program newsletters, youth education through Drug Abuse Resistance Education, and hotlines and other provisions for the easy transfer of information between the police and the community. COMBAT aims to enhance the quality of life, reduce drug use, and accomplish five other goals through three types of activities: (1) improved drug law offense processing, (2) enhanced police-community relations, and (3) intensified drug crime prevention.
