This chapter discusses Article 5 of the ATT. Article 5 sets out the obligation to implement the ATT at the national level, in particular by establishing and maintaining a national control system for the transfer of conventional arms and integral parts and components and for ammunition/munitions. It should be noted that this is the only provision that obliges states parties to set up national mechanisms to regulate conventional arms transfers, as opposed to transfers of parts and components and ammunition/munitions. In addition, Article 5 offers detail on the scope of the treaty outlined in Article 2(1) by requiring each state party to regulate battle tanks, armoured combat vehicles, large-calibre artillery systems, combat aircraft, attack helicopters, warships, and missiles and missile launchers in accordance with the United Nations Register of Conventional Arms (UNROCA) and small arms and light weapons, as defined under the 2005 International Tracing Instrument.
