Defense Intelligence Agency

The Defense Intelligence Agency or DIA was a pre-War intelligence agency of the United States.

Background
The DIA's activities were classified and their locations secret. The secrecy allowed the agency to maintain an extensive intelligence network abroad and on the domestic front, comprising signals intelligence and data processing.

The DIA lead the search for and the apprehension of Wan Yang, a Chinese field agent, in Point Lookout. Yang was subsequently transferred to Turtledove Detention Camp for interrogation, and the DIA office under Lt. Krumfolz declined comments to the press and to diplomats, deferring to DoD public relations for any statement.

PAM
The DIA's technological capabilities were more advanced than other branches of the government. The P.A.M. Initiative was an ambitious and successful project, resulting in the creation of a data processing system that allowed the agency to predict the actions of foreign entities. PAM could provide analyses or suggest corrective measures to achieve specific goals, such as the stabilization of the Taiwan Straight region, following the Pascale Incident.

As it developed, PAM was used not just to process data, but to determine the likelihood of various military scenarios playing out, such as determining the likelihood of a coordinated nuclear strike by China and the USSR six months into the Chinese invasion of Alaska, in June 2067.

Partners
The DIA commissioned work from outside corporations, such as RobCo for the creation of the custom, multi-million dollar mainframe CRYPTOS. This system was intended for use in "a top secret government project," but the DIA pulled the contract just as work was completed on the mainframe.

The DIA also contracted with the Vault-Tec Corporation for the development of Project SERAPH. Seraph was an experimental Class-IV hypergenetic virus intended to penetrate high-security defense and intelligence mainframes.

Locations

 * Naval recruiting center: Field office responsible for apprehending Wan Yang.
 * The Switchboard, Massachusetts: Below the Lexington Slocum's Joe shop, used to test the Predictive Analytic Machine. The facility was repurposed into the headquarters of the Railroad until the Institute attacked and put the facility out of action. Further Railroad missions have the Sole Survivor seek caches left around the Commonwealth by the DIA.


 * Monitoring stations A-31 and B-19: In November 2075, agents here reported unknown entities, rumored to be stealth subs of the Chinese.
