My favorite quote is from Sun Tzu:
Sun Tzu Words on Intelligence
"Intelligence is of the essence in warfare - it is what the armies depend upon in their every moves".
There are 5 kinds of spies that can be employed:
local [yin] spies, inside spies, double agents, expandable agents, and un-expandable agents.
When the 5 kinds of spies are all active and no one knows their methods of operation [tao] this is called the imperceptible web and this is ruler's treasure.
Local spies are the enemy's own countrymen in our employ.
Inside agent are enemy officials we employ.
Double agents are enemy spies who report to our side.
Expendable agents are our own agents who obtain false information we have deliberately leak to them and who then pass it on to the enemy spies.
Un-expandable agents are those who return from enemy camp to report.
