Imp IMP-4E

The Imp IMP-4E is a 100-ton assault juggernaut, cruising at 32 km/h and topping out near 54, slow going for a machine this size. Where the IMP-1A carried Medium Pulse Lasers in the left arm and both side torsos, the 4E replaces them with ER Medium Lasers, adding a second ER Medium Laser in the right arm beside the LRM 20 and fitting an ER Medium Laser in the head in place of the original's Small Laser. A pair of ER Small Lasers now sit in the left leg and right leg, weapons the 1A never carried, while the twin ER PPCs in the left torso and right torso and the paired Medium Pulse Lasers in the center torso carry over from the earlier machine, along with the Artemis IV fire-control system in the right arm and the CASE installation in the left torso. Heat sinks rise from 18 to 21, all double type. It is built as a command 'Mech and is known as a maintenance-intensive design, and GM Blackwell produces it at Outreach, with Arc-Royal MechWorks also turning out the type at Arc-Royal.
