''Terminate, with extreme prejudice''

''SAIGON. - In a nondescript white concrete-block building on the outskirts of this capital city, an International Business Machines Corp. Model 1430 computer runs 24 hours a day grinding out one of this war-torn country's most valuable products: Military intelligence. The building houses one of four intelligence centers scattered around Saigon. Using automatic data processing equipment, this intelligence setup - the biggest operated by the United States outside Washington and the biggest ever used against a single enemy - is now handling a massive assortment of facts and figures aimed at winning the Vietnam war. More than 100,000 separate items are being added to the system's computerized files each month; a 60-ton haul of enemy documents seized last January is still yielding valuable information. Tens of thousands of IBM punch cards help keep tabs on the foe; they bear detailed identification of captured Communists and Vietcong suspects.''

2. "Fully leverage internal and external NSA partnerships to collaboratively discover targets, find their vulnerabilities, and overcome their network/communication defenses."

''Shortwave Numbers Stations are a perfect method of anonymous, one way communication. Spies located anywhere in the world can be communicated to by their masters via small, locally available, and unmodified Shortwave receivers. The encryption system used by Numbers Stations, known as a one time pad is unbreakable. Combine this with the fact that it is almost impossible to track down the message recipients once they are inserted into the enemy country, it becomes clear just how powerful the Numbers Station system is.''
