Fortifications are defensive positions that can be manned by either allied or enemy forces and are a moderately common sight in the Battalion Wars saga. The hazard which they present depends on the weapon that they have. In the first Battalion Wars, there are MG Nests, MG Bunkers, MG Towers, and Pillboxes. Bazooka Veterans, Tank shells, and mortar/artillery fire are extremely useful for clearing these out. In BWii, several variations, including RPG and Anti-Air Towers, were added. Empty MG nests are usually rare but when you see one, it means there's going to be a tough defensive fight ahead. In BWii, Auto-Guns make their appearance as a non-controllable sentry for friendly and enemy facilities. There are also fortifications specially-made for Naval usage, such as Naval Guns.
