“There
is no teacher but the enemy. No one but the enemy will tell you what
the enemy is going to do. No one but the enemy will ever teach you how
to destroy and conquer. Only the enemy show you where you are weak. Only
the enemy shows you where he is strong. And the rules of the game are
what you can do to him and what you can stop him from doing to you.”

Mazer Rackham

“A nation that makes a great distinction between its scholars and its
warriors will have its laws made by cowards and its wars fought by
fools.”

Thucydides
