The OSCE participating States agree that the scope for addressing stockpiles of conventional ammunition, explosive material and detonating devices in surplus and/or awaiting destruction has to be as broad as possible. The OSCE Document on SCA includes conventional ammunition, explosive material and detonating devices of land-, air- and sea-based weapons systems. Ammunition used for weapons of mass destruction (nuclear, chemical and biological) is excluded.

The following broad categories serve as an indicator, bearing in mind the wide range of categories and components of conventional ammunition, explosive material and detonating devices in surplus and/or awaiting destruction (not listed in order of priority): 
 
(i) Ammunition for small arms and light weapons (SALW); 
(ii) Ammunition for major weapon and equipment systems, including missiles; 
(iii) Rockets; 
(iv) Landmines and other types of mines; 
(v) Other conventional ammunition, explosive material and detonating devices.
