In a huge military parade to mark National Army Day, Iranian troops showed off the "Kamin-2" missile system as it was driven on the back of a truck through the streets of Tehran.

A low-altitude missile system, the "Kamin-2" is designed to confront military drones, unmanned aerial vehicles (UAVs) and low-flying planes.

This latest military system is an upgraded version of the Mersad missile system.
