Defense News reports that “Andrew Marshall — a Pentagon institution who influenced policy makers from the Cold War to today — has signaled his intention to step down in January, according to sources.”  

“Marshall, 93, heads the Office of Net Assessment (ONA), which months ago was spared the budget ax as part of a restructuring of the Office of the Secretary of Defense.”  

“Having founded the Pentagon’s internal think tank in 1973, Marshall is the only director it has ever known. His influence over the decades on defense policy analysis in Washington has been vast.”
