Format the SCG according to mandatory DoD standards, including cover pages, general instructions, classification tables, and declassification/downgrading instructions. Comprehensive Information Analysis Conduct rigorous analyses to determine which elements of information warrant protection. Assess capability performance, uniqueness, technological lead time, element of surprise, vulnerabilities, critical design elements, and manufacturing technology. Draft precise "Value," "Damage," and "Unclassified" enhancement statements for classified line items to clearly articulate the rationale and threat impact to derivative classifiers. Classification & CUI Determinations Determine the valid reason for classification (per E.O. 13526 Section 1.4), the appropriate classification level, and the specific duration/declassification event for each element. Identify and appropriately designate elements of information meeting the criteria of Controlled Unclassified Information (CUI) and apply proper dissemination controls (e.g., FOUO, REL TO). Horizontal Coordination & Deconfliction Conduct horizontal coordination across DoD Components, Military Services, agencies, and foreign disclosure offices. Review existing SCGs via the Defense Technical Information Center (DTIC) index to ensure consistent classification and prevent overlapping conflicts with other programs or Special Access Programs (SAPs).

Contractor personnel must be U.S. Citizens possessing an active DoD Secret security clearance on day one of performance. Work shall primarily be performed on-site at NSWC Crane or Cleared Contractor Facility Location to facilitate daily interaction with the OCA and engineering teams.
