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