I see it is not an independent impartial review.
Purpose
The panel’s mission was (1) to identify personnel policies and practices within the Department of Defense (DOD) that, by reason of their political orientation or other potential for divisiveness, reduce military readiness, impede military recruiting, and undermine retention; and (2) to recommend actions necessary to ensure that the Armed Forces are prepared to protect the nation for the foreseeable future. The primary audience for the panel’s final report are the policymakers in Congress, Administration officials, and the American public.
So it clearly has an agenda (My bold.)
The review was set up by the Heritage Foundation which is a self appointed think tank rather an impartial body
Now more than ever, the American people need a champion to preserve the great American experiment and everything good and just that it represents. That’s why The Heritage Foundation exists. We champion policy solutions that benefit all Americans. But Heritage is also much more than a think tank. Every day, Heritage works in our nation’s capital to build an America where freedom, opportunity, prosperity, and civil society flourish.But unlike so many other organizations in Washington, D.C., The Heritage Foundation’s focus isn’t on putting more power into the hands of government—it’s on returning power to the people.
The report should be read in that light.
