Ultimate War (Pathfinder)

This rules supplement expands Pathfinder mass combat beyond land warfare to include aerial, naval, underwater, and siege operations. It introduces modular unit building for combined-arms forces and streamlined squadron-level battles, along with command boons, aerial and naval vehicles, specialized tactics, and ground tactics against fliers. Siege rules cover blockades, bombardment, incendiaries, plague, infiltration, and escalades, supported by mundane and magical siege weapons, artillerists, and additional siege tactics. The systems integrate with the kingdom and mass combat rules from Ultimate Campaign and related supplements.
