N-40 Heavy Force Field
This force field requires a harness system and is slightly heavier than the N-12 or N-20. This is the usual limit for infantry force fields. An E-Clip will power the force field for only 4 hours of continual use.

This N-40 Heavy Force Field was a boon from the Calgary Arena that McGreggor used aide his fight with the Cyborg.
