Editing Operation

{{Era|Human|UNSC|HCW}}
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, [[battle]]s 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.
