Armies should be privately organized.

There would be less wars, no useless, unprofitable wars, less soldiers, higher wages for soldiers, and damages done on civilians and civilian properties would have to be replaced by the military companies. They would also care a lot about only attacking where profits can be expected, where they don’t risk loosing too much soldiers, and they would require the consent of the attacked party and priory agree on the terms of the fight. It is only statal armies that go into useless wars, because they can simply force their citizens to go to war for cannon fodder and not even pay them something, because they dispose of a next-to unlimited amount of soldiers for free, something no private army could ever afford.
