Since the nations of Esoteric are all Camarilla controlled, they do band together to fight off any outside threat. While there may be wars between nations based on stupidity, the majority of Esoteric lives in peace.
I'm not going to list every nation at the moment with specific military stats, but each nation does have their own navy, air force, and army. Energy weapons are common as are lasers. The land based military is on an FT scale, though jet fighters are still on a PMT level. The majority of land based military could be described as an earthbound robotech type mecha.
