They are just like all other government bureaucrats.
They have a systems sense and know which way the winds are blowing.
Every government department and agency is a political tool, all of them, no exception.
The DoD is one of the better ones because at least the brass has to earn their right (experience, professional development, degrees...) to become top tier managers although their civilian leadership is ever much as bad... Whereas in some other government agencies you get some real yokels in charge, i.e. State Department and many of the Ambassadors...
These guys in the DOD are the worst of the worst. The commie rock suckers have created a network to bring to the top other like minded sellouts. True patriots get forced out by these parasites. They sold their souls to be a Washington elite kiss ass. Our soldiers deserve better, our country deserve better.
