As of December 3070 (and still by August 3084),[5] the Inquisitor is considered one of the most well-known SecurityMech designs, named alongside the likes of the Copper, Guard and Pacifier.[1]


This heavy (by IndustrialMech standards) SecurityMech was invented by Irian Technologies, Unlimited in 3062[3] exclusively for the defense of all IrTech facilities throughout the Free Worlds League. Since its introduction it rapidly proliferated throughout the Inner Sphere due to IrTech's decision to sell it on the open market at the end of the Jihad.

During the Jihad, large numbers of Inquisitors were used by the Word of Blake's police and industrial security forces, militia units, and TerraSec. Though generally less effective than a BattleMech, they were deployed in large numbers that caused problems during Operation SCOUR.[2]

Weapons and Equipment[edit]

The initial Inquisitor is widely thought to be closer to any BattleMech than any other SecurityMech. The ER Medium Laser and SRM-4 are capable of inflicting respectable damage on armored targets and the twin machine guns are effective against infantry. These weapons are controlled by Advanced Fire Control. Two tons of Communications Equipment allow the pilot to coordinate effectively with other security forces. An Ejection Seat and seven tons of Heavy Industrial Armor protect the pilot, but the design was criticized because it lacked CASE.

    The only variant authorized by Irian, this Inquisitor was introduced in 3132 and replaces the Communications Equipment with a Beagle Active Probe and CASE II system from the Inquisitor II.[2] BV (2.0) = 664[6]
