US Cyber Command, the main elite military cyberwarfare unit, is under the joint leadership of the NSA director. What they're doing now is moving the techniques "down-market" so that ordinary units have cyber capabilities as well. Think JSOC vs. regular infantry. You need both to be effective.

Amusing side note, the MD5 hash of CYBERCOM's mission statement, "9ec4c12949a4f31474f299058ce2b22a", is to my knowledge the only hash emblazoned on an agency seal.
