Tactical nuclear weapon

A tactical nuclear weapon (TNW) or non-strategic nuclear weapon (NSNW) is a nuclear weapon that is designed to be used on a battlefield in military situations. Generally lower in explosive power, TNW are defined in contrast to strategic nuclear weapons, which are mostly designed to be targeted against military bases, cities, industries, and other strategic forces. Though hundreds of types of tactical nuclear weapons have been developed and deployed since the 1950s, none have ever been used in combat.
