Operation

An operation is a planned military offensive conducted by a military force, generally against a specific enemy objective or group of objectives. Operations can be large scale military campaigns, battles or small, covert insertions. Operations receive unique code words to distinguish themselves from other actions without giving away sensitive information that could be intercepted by enemy forces.
