Homemade Terrorist Weapons
An important intelligence role is to discover illegal weapons and explosives before they can be used by terrorists or insurgents.
The recovery by Security Forces of smuggled, illegally-held commercial weaponry, like the AK variant assault rifle at the back of the photo, often leads to terrorist groupings developing their own home-made 'improvised' weapons.
The small mortar, fired by a shotgun cartridge, was recovered from Loyalist terrorists during a search in Northern Ireland during the 'Troubles'.
The home-made pistol and 'zip gun' were recovered from Republican terrorist groups, also in Northern Ireland.
