Our modern army is quite efficient as an all- volunteer, professional fighting force.
But let me suggest that that is not the central, or even the principal, role of the Army in our society and throughout our history.
By “Army,” I am writing of all the armed forces, but the Army is the biggest and the oldest of our branches of the service and I’ll just use “army” to mean all.
All of you ex-Marines, Navy, Air Force, Coast Guard types just cool it for now.
You may legitimately say, “But what is the role of the army if not to defend our country?”
