It is passive because the action was done by the 'commander' and the noun (SOP) would be the direct object in an active sentence. In other words, the subject of the sentence is being acted upon, not acting.
The commander does not have to sign the document. An SOP document is a standard operating procedure document that tells someone how to carry out a task.
