@Jeff Beyle , Thank you for your question.
At the time of writing, Azure Government has the broadest compliance certifications of any cloud provider on the market. FedRAMP Moderate and High provisional authorizations meet DoD compliance standards at Impact Levels 2, 4, 5, and NIST 800-171 controls satisfy DFARS and ITAR requirements. Two new regions for Azure Government Secret and a third announced region provide extended support to meet Department of Defense Impact Level 6 (IL6) and Director of National Intelligence (DNI) Intelligence Community Directive (ICD 503) accreditation with facilities at ICD 705. For more information please refer to this document.
Here is an overview of the Department of Defense (DoD) in Azure Government.
