Well not really, maybe they got the best military but according to the corporate guide, Knight only owns like 23 percent of the company...his rivals own like 36 percent together(with 12 percent owned by the Draco foundation).
However Knight's controlling share is in weapons research so yeah he may have the best weapons but all Megas(Corporate court), Dragons, major powers, even secret societies combined will smash Knight so it will be bloody.
As for the powers who want Knight's head I can say that Aztechnology, Renraku, Saeder krupp, Maersk(AA), Proteus(AA)have axes to grind vs. Ares.
Well Aztechnology hates Ares for its support of teh Yucatan rebels and the Amazonians and see Ares firmly behind the CAS. All the rest including Azzies see Ares as a competitor in their arms industries and wish to see Ares taken down or eaten by them since Ares is top dog in this field.
Also the Dragon groups and cults have a proviso in exterminating the bugs whenever they are found, so expect the Dragons to try to take out Damien Knight...interesting as said earlier that the Draco foundation controls like 12 percent of Ares. Maybe we can have an alliane with Vogel and the Draco to kick out Knight and control Ares. Ares would be a powerful tool for Dragons not with Saeder Krupp.
