Esper was fired after he opposed deploying troops against BLM protestors. He was replaced by a former defense contractor last november who made the news by blocking the Biden transition and also breaking the longstanding guideline to not put ex-military in that position. The acting SoD was put in as a last minute loyalist to repeat the show of removing troops from Afghanistan prior to the election and then obviously put them back. Same dance they did about 2 years ago. Biden's pick is also ex-military... just so nobody thinks I have any delusions about Biden's foreign policy going forward.
