I always find Wikileaks a source of amazement. The latest leaks included:
UK Counter Insurgency Operations Doctrine 2007
Secret Ritual of Sigma Phi Epison 1984
US Special Forces counterinsurgency manual FM 31-20-3
UK Tactics for Iraq and Afghanistan 2007
US Suppression of Enemy Air Defense chapter 2
Venezuela buying millions in spy equipment from US Phoenix Industries 2000
US Army CALL 05-6 Operation Enduring Freedom III 2005
UK and Danish Rules of Engagement for Iraq 2006
Some very interesting reading.
