MASS DESTRUCTION
§2M3.1. Gathering or Transmitting

(a) Base Offense Level: 
  (1) 42, if top secret information
    was gathered or transmitted; or
  (2) 37, otherwise.
Commentary
Statutory Provisions: 18
  U.S.C. § 794; 42 U.S.C. §§ 2274(a), (b), 2275.
Application Notes: 
1. "Top secret information" is information that, if disclosed,
  "reasonably could be expected to cause exceptionally grave damage to the national
  security."  Executive Order 12356.
2. The Commission has set the base offense level in this subpart on the assumption
  that the information at issue bears a significant relation to the nation’s
  security, and that the revelation will significantly and adversely affect security
  interests. When revelation is likely to cause little or no harm, a downward
  departure may be warranted. See Chapter Five,
  Part K (Departures).
3. The court may depart from the guidelines upon representation by the President
  or his duly authorized designee that the imposition of a sanction other than
  authorized by the guideline is necessary to protect national security or further
  the objectives of the nation’s foreign policy.
Background: Offense level
  distinctions in this subpart are generally based on the classification of the
  information gathered or transmitted. This classification, in turn, reflects
  the importance of the information to the national security.
