Maybe part of it. More likely:
The Union/US had assistant secretaries of war already. The Confederate army was expanding rapidly and perhaps the exigencies of the war required some assistants in the War Office.

Edwin Stanton didn't have a military background either. And had as much (as little) executive experience as Judah Benjamin.
The assistant Secretaries of War CSA included Robert Ould (a lawyer and prewar militia general) and John A. Campbell (ex-Justice of the US Supreme Court). Not a lot of military experience there, either. The assistants appear to have been chosen for the legal expertise, as a lot of legal questions plagued the War Department.
