The Improved Advanced Tactical Missile 12 or iATM 12 is the largest of the improved missile launchers developed by The Society. Capable of firing the standard ammunition types used by Advanced Tactical Missile launchers as well as Improved Inferno Ammunition and Improved Magnetic Pulse Ammunition, the iATM 12 offers significant improvements over its progenitor.

Like the standard ATM 12, the iATM 12 uses an advanced targeting system. Unlike the ATM, this system is based on Streak SRM technology which ensures that the missiles will only fire if there is a solid target lock. (This was probably beneficial to the poorly-trained MechWarriors available to the Society.) Unlike typical Streak missile systems, the iATM can fire indirectly to provide fire support to friendly units. The downside to this is that the Streak system doesn't operate when firing indirectly.[1]


This weapon was only produced by the Society, and therefore no Inner Sphere models exist.
