Iran tested its state-of-the-art missile systems in its large-scale air defense drills codenamed Modafe'an-e Aseman-e Velayat 7 in the Southern parts of the country on Wednesday, December 28, 2016. The Iranian-made ‘Sayyad-3’ missiles was test-fired from the Talash air defense system. Wednesday marked the third and final day of Modafe'an-e-Aseman-e Velayat 7 maneuvers featuring weapons of the Iranian Army and the Islamic Revolution Guards Corps (IRGC). On Tuesday, December 27, 2016, two home-made missile defense systems, Talash (Endeavor) and S-200, were deployed in Southern Iran during the second day of massive air defense drills underway in the region. For the first time, the new home-made Talash air defense missile system has been deployed in the Southern parts of the country. The Talash is a long-range air defense missile system capable to destroy aerial targets flying at low, medium and high altitudes at a maximum range 200 km. The Sayyad-3 missile launched from Talash system is able to intercept aerial targets at a maximum raqnge of 150 km. The Talash can also fired Sayyad-2 missiles against air targets at medium altitudes. Each unit of the Iranian-made Talash system includes three vehicles, a mobile truck launcher carrying the missiles and two command and control vehicles. The latest version, the Talash 3 was unveiled in September 2014, which has a range of more than 200 kilometers.
Irgc (aka sepah) operates independently from Iranian Army (aka Artesh) but ultimate general command of both is the General Staff and further up. Sepah can operate its own missions or complement the artesh's missions. I also suspect they act as a counter balance to the artesh. Similar relations include: SANG (Saudi Arabian National Guard), a counter-balance to the Saudi Armed forces. Other rumored examples: PAP (People's Armed Police) & PLA; National Guard Russia & Russian Armed Forces; CAPF (Central Armed Police Forces) & Indian Armed Forces.
