I don't have specific information about any changes made to the Defense Department's domestic abuse policy in December 2021 or beyond. It's important to note that policies and regulations can be subject to regular updates and changes based on various factors, and I may not have access to real-time information.
To get the most accurate and up-to-date information on the Defense Department's domestic abuse policy changes, I recommend checking official government sources, such as the U.S. Department of Defense website, or reputable news outlets that cover military and defense-related topics. These sources should have the latest updates on any changes made to the domestic abuse policy within the Defense Department.
