This military purge seems to be a pattern. Obama also apparently purged the civil service of Republicans(I found article about the plans in 2009). There were men who were Bush political appointees AT ONE TIME, and later became civil service employees. Obama made a retroactive rule to get rid of them since they were once political.
Obama has also purged at least one, if not more, Inspectors General. It is a pattern of civil and military purges. Helps to explain why there has been so little pushback inside the Regime against Obama/Jarrett or whomever is devising the plans.
