There are already regulations established to address this issue. There are standards already in place. There are numerous training programs that Service Members are required to conduct and participate in. There are already security screenings and background checks. There are laws to ensure good order and discipline. Anyone violating those standards should be, and have been, reported through the appropriate channels and actions taken.
Two lines in the article stand out: "There are questions that need to be answered, like what constitutes extremist activity? What is permissible in looking for extremists in the ranks?"
The fact these questions are even asked - at least for me - explains exactly what this is. A political ploy, and a lesson to all Service Members that you will watch what you say and do. Nothing more, nothing less. This is a mechanism to ensure obedience to the current administration - not the Constitution as the Oath administered demands.
That's my personal opinion.
