A new protagonist in the war stepped into the light when Operation: Elysée began: MedTec is originally a U.N. interstellar company and a subsidiary of ONI Technologies.
This company sells its cutting edge medical services to all sides involved. Everything that can preserve the existence of a fighter is available: Therian nanotechnology, experimental Red Blok cloning treatment, Karman relaxation techniques, etc. All it takes is payment, with money for those who know of the concept, more often in resources of all sorts.
MedTec is not a neutral power and no one will hesitate to shoot at a medical container being used by the enemy. The nurses and doctors working for this company are greatly rewarded for the risks they take.
General staffs on every side can only speculate when they discuss the deals they suspect MedTec has sealed with their enemies. The U.N.A. and the Karmans have an immediate interest: ONI Tech has access to collectivist cloning techniques and to some extent Therian technologies. Neither the Red Blok nor the Therians had any reason to accept a neutrality deal at first. It wouldn't have been particularly favourable to them since it made their advantages available to their enemies.
