Always verify applicable clauses in the actual solicitation. Clause applicability depends on contract type, value, and specific program requirements.
Frequently Asked Questions — DoD Contracting
Start with an active SAM.gov registration and a capability statement tailored to DoD needs. Identify the specific military department or defense agency most relevant to your services — Army, Navy, Air Force, DLA, and DISA each have distinct contracting offices and priorities. Attend DoD small business events and industry days to build relationships with contracting officers before solicitations are released.
The Cybersecurity Maturity Model Certification (CMMC) 2.0 is DoD's framework for ensuring contractors protect Controlled Unclassified Information (CUI). CMMC Level 1 (self-assessment) applies to contractors handling Federal Contract Information (FCI). CMMC Level 2 (third-party assessment) applies to contractors handling CUI. Not all DoD contracts require CMMC — check the solicitation for DFARS 252.204-7021 to determine applicability.
DoD is required to award at least 23% of prime contract dollars to small businesses annually. Specific goals exist for 8(a) firms (5%), HUBZone firms (3%), women-owned small businesses (5%), and service-disabled veteran-owned small businesses (3%). Many DoD solicitations are explicitly set aside for small businesses, and even large contracts often have small business subcontracting plans.
The Defense Federal Acquisition Regulation Supplement (DFARS) adds DoD-specific requirements on top of the base Federal Acquisition Regulation (FAR). DFARS clauses cover cybersecurity requirements, specialty metals restrictions, ITAR compliance, IP rights, and other defense-specific topics. Any solicitation with a DFARS clause number (252.XXX-XXXX) means you are in DoD territory and need to understand the additional requirements.
