Autocratic government. That is where one person reigns supreme. King John had no restrictions on his power. He was forced to sign the magna carta. That limited his power. That gave the nobles power. Their was a group of nobles that I think later formed the basis of parliament although wasnt exactly parliament.
The Selective Service Act of 1917 or Selective Draft Act (Pub.L. 65–12, 40 Stat. 76, enacted May 18, 1917) authorized the United States federal government to raise a national army for service in World War I through conscription.
The Senate has the constitutional power of Confirming presidential appointments.

Combatants may of course be attacked unless they are out of action, i.e. hors de combat. Civilians are protected from attack but lose this protection during any period in which they take a direct part in hostilities. The protection of civilians applies to both enemy civilians and one's own civilians.
