Plug-and-fight is the military equivalent of plug and play as applied to commercial and personal computer systems. Plug-and-fight refers to the capability of certain large military systems such as the Medium Extended Air Defense System(MEADS) to automatically recognize and assemble various system elements, like sensors, weapons, and control nodes, into a single integrated supersystem or system-of-systems. Plug-and-fight systems can be rapidly reconfigured without interrupting operations – adding, removing, and rearranging system elements in response to evolving threats and changing defense strategies. The architecture of such modular systems is often described as netted-distributed.
