Arms trafficking or gunrunning is the illicit trade of contraband small arms and ammunition, which constitutes part of a broad range of illegal activities often associated with transnational criminal organizations. The illegal trade of small arms, unlike other organized crime commodities, is more closely associated with exercising power in communities instead of achieving economic gain. Scholars estimate illegal arms transactions amount to over US$1 billion annually. keep track of imports and exports of several of the most dangerous armament categories, the United Nations, in 1991, created a Register for Conventional Arms, however participation is not compulsory and lacks comprehensive data in regions outside of Europe. Africa, due to a prevalence of corrupt officials and loosely enforced trade regulations, is a region with extensive illicit arms activity. In a resolution to complement the Register with legally binding obligations, a Firearms Protocol was incorporated into the UN Convention on Transnational Organized Crime, which requires states to improve systems that control trafficked ammunition and firearms.
