Jacoby immediately took steps to transform DIA to improve its ability to provide sustained and focused military intelligence support to the warfighter, defense planners and policymakers. Under Jacoby’s watch, DIA successfully applied a dynamic, innovative approach to acquire and provide a portfolio of intelligence capabilities of the needed breadth and depth to support military operations in Afghanistan, Iraq and the war on terrorism. During this period, DIA forward-deployed hundreds of military and civilian personnel to conduct high-impact, all-source intelligence operations in Afghanistan, Iraq and around the world as part of the broader struggle against terrorism. As a result of its superb responsiveness and agility, the Agency enhanced the country’s ability to confront the rapidly evolving security challenges presented by the asymmetric threat of terrorism.

DIA’s capabilities went beyond providing support to military operations. DIA responded quickly to the humanitarian disaster created by a tsunami in the Indian Ocean, and DIA analysts provided insightful medical intelligence support to the relief effort by forward-deploying analysts to the U.S. Pacific Command. There, they assessed infectious diseases and the environmental health risks in the area, a mission routinely done for U.S. forces that deploy overseas.

During Jacoby’s tenure, DIA distinguished itself by exceptionally meritorious achievement providing military intelligence support to the to the president, the secretary of defense, the chairman of the Joint Chiefs of Staff, and to the U.S. and allied warfighters, and was awarded its seventh Joint Meritorious Unit Award.
