Was the purging of approx 200 capable senior officers necessary and what impact, if any, has it had on the Officer Corps?

Corporate America conducts purges of senior leaders all the time, sometimes it is by design and sometimes for necessity. Rotate the stock I say. A few years ago the Marine Corps was super too heavy at the O-6 level and it impacted promotions and upward mobility because the Colonels were just sitting around as long as they could. If I purge 200 senior field grades, that is opening up budget for more trigger pullers.

My observation of the forced retirement of flag officers was to politicize the military. Obama replaced many capable officers who could say no, to a officer corps of deep state yes officers. As to battalion and company grade officers, it is appropriate to draw down the officer corps to acceptable levels r ratios with number of enlisted military.

Across the board cuts are difficult - no matter what organization and no matter what level the personnel. However, in large bureaucracies - such as the DoD - it's the simplest way to achieve the intended results.
The DoD has continued to inflate the senior officer ranks that is disproportional to the service members they command. The problem was WITH leadership, to answer your question, Capt Jeff S..
