Hi, Chuck, I am Jeronimo, Thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you.
Obtaining a copy of the DoD Windows 11 LTSC (Long-Term Servicing Channel) ISO requires following official channels to ensure compliance with DoD policies and security requirements.
Your Information System Security Officer (ISSO) or local IT support team should have access to the necessary software and can guide you through the process.
