Unplugging from the Muddle in the East may leave the Army unable to fight without heavy contractor support. Contractors, by and large, cost three times the cost of soldiers, The knowledge base of operational and strategic level logistics, formerly known as combat service support (CSS), is becoming lost to the uniformed, and will atrophy with the end of contracting for CSS in a post war cost cutting environment.
The Army Reserve was the home of combat service support units trained to support the contingencies of the Active, Guard, and Reserve fighting forces. The doctrine has virtually disappeared. The Army Reserve was home to CSS as there is little to do on full time active service to justify the expense. The Pentagon's visceral fear of Weekend Warriors has gutted the Army before, and it appears that national survival or defeat in battle in the future is a more acceptable outcome that restoring combat service support to those in uniform, and subject to military orders.
A solid nail in the coffin is the recent deletion of the term "combat service support"" from the lexicon of official Army terminology.
