That's silly. Read George Washington on the subject, or some of the other command of the Continental Army - there was an army, there were militia, and they sure as hell were not the same things.
Or here:

Fast forward eighty years, and the difference between the Confederate Army and the secessionist militia became especially striking after the war - when various militia simply refused to disband, and became outlaw gangs

The recurrent problem of discipline inevitable with militia is what led to the establishment of the US military, and has since led to that military's usurping all foreign and some domestic combat functions of the various militia in the US, with the sheriffs and police taking some of the domestic violence chores.
That would be clear evidence - in fact proof - that the militia was distinct from the military. The standing militia were favored, the formation of a standing army was opposed. The amateur armed populace was favored, the trained professionals holding a monopoly on arms and violence opposed.
Again drawing a clear distinction between military and militia.
