OK, how's this:
Here is a link to the U.N.'s Disarmament site. If you want the info straight from the source, it is here:
http://www.un.org/disarmament/
Links include:
Conventional Arms
Small Arms / Armed Violence, Arms Trade Treaty, Transparency Registers, Ammunition, Landmines, Certain Conventional Weapons & Cluster Munitions
Should provide the info the OP requested. Although, there
may be a boat load of questions about the international legalize used.
