The Xenoforce Reborn mod takes the classic Xenoforce mod from CNC Generals and re-invisions it on the CNC3 engine with new units and new designs. The new armies that are currently scheduled to be in the mod are the Earth Federation, ZEON, the Invid, and the Earth Robotech Defense Force. We also have heavily modified the original CNC3 armies, giving the GDI, NOD, and Scrin a much more dynamic gameplay experience. This mod is NOT FOR PROFIT and NON-commercial based.
NOD's cybernetic division is known for building cyborgs that they then sell to other countries and warlords for protection. They are also used in the field to help protect the more advanced teams in the field. Here's a pic of the Inquisition with a Cyborg Protector. In practice this is actually very useful as the Cyborg will fire it's weapons as it and it's team move into range for the Inquisitions flame throwers.
As far as the way this works with the upgrade system the Inquisition, Sisterhood, and Confessors will all have the Cyborg Protector with them. Depending on the upgrade you pick it will either upgrade the Protectors weapons and/or the teams weapons.
