John Paul Stevens,
Perpich v. Department of Defense…
“ Lexicographers and others define militia, and so the common understanding is, to be 'a body of armed citizens trained to military duty, who may be called out in certain cases, but may not be kept on service like standing armies, in time of peace.' That is the case as to the active militia of this State. The men comprising it come from the body of the militia, and when not engaged at stated periods in drilling and other exercises, they return to their usual avocations, as is usual with militia, and are subject to call when the public exigencies demand it. ”
