 Slingshots have been used as military weapons, but primarily by guerrilla forces due to the primitive resources and technology required to construct one.Such guerrilla groups included the Irish Republican Army; prior to the 2003 invasion of Iraq, Saddam Hussein released a propaganda video demonstrating slingshots as a possible insurgency weapon for use against invading forces.Slingshots have also been used by the military to launch unmanned aerial vehicles (UAVs).
