In nuclear strategy, a counterforce target is one that has a military value, such as a launch silo for intercontinental ballistic missiles, an airbase at which nuclear-armed bombers are stationed, a homeport for ballistic missile submarines, or a command and control installation. The intent of a counterforce strategy (i.e., attacking counterforce targets with nuclear weapons) is to disarm an adversary by destroying its nuclear weapons before they can be launched, thereby minimizing the impact of a retaliatory second strike. However, counterforce attacks are also possible in a second strike, especially with weapons like UGM-133 Trident II. A counterforce target is distinguished from a countervalue target, which includes an adversary's population, economic, or political resources. In other words, a counterforce strike is against an adversary's military while a countervalue strike is against an adversary's cities. A closely related tactic is the decapitation strike, which by destroying an enemy's nuclear command and control facilities similarly intends to eliminate or reduce their ability to launch a second strike.
