"At stake is a fundamental component of the framework of US constitutional democracy. It begins with the principle, enshrined in law, that military forces exist to protect the country from existential threats — such as an invasion or rebellion — not to enforce the law.
Most fundamentally, the founders of the American republic understood very clearly that concentrated military power, loyal to a single man, could be used to achieve total control by that person. And they had a historical example in mind: Rome — a republic governed by the people and the Senate — was transformed into an empire ruled by an emperor as a result of the Roman army being turned against its citizens."
