1-15. Like us, peer threats view the battlefield, their own instruments of power, and an opponent's instruments of power as a collection of complex, dynamic, and integrated systems composed of subsystems and components. They will employ systems warfare to identify and isolate critical subsystems or components that give friendly forces the capabilities necessary to accomplish their mission. Their integrated fires complexes and air defense systems represent a significant systems warfare capability. To counter these tactics, commanders must examine their own systems to identify potential vulnerabilities that the enemy may attempt to exploit and develop plans to protect those vulnerabilities. Commanders must also analyze adversary and enemy systems, identifying critical vulnerabilities and applying resources against them.
