Patriot operating on its lonesome is a tenuous proposition at best; while a first-rate system technologically, the Patriot cannot be used to full effect if it is divorced from air defense doctrine. Patriot systems are limited to pinpoint defense of major assets and are designed to operate in tandem with air defenses engaging targets at higher and lower altitudes. Without these additions, Patriot will have too many threats to engage and the result will either be porous coverage that doesn’t protect its defended assets, or coverage that quickly subsides when Patriot runs out of interceptors.
