"Government doesn’t like its departments messing outside their areas. Espionage belongs to the D.S.A. and the C.I.A. and the F.B.I. They each have their slice of the pie, but the Army’s got squat in the way of its own authorized shadow resources. Yup. All adds up to Army. All of Yates’s tie-ins were groundpounder issue , and the Army’s the only service flying attack choppers."
