Alexander explained in response to a question from Rep. Trent Franks (R-AZ). "We maintain that access, gain deep understanding of the adversary, and develop offensive capabilities through the advanced skills and tradecraft of our analysts, operators and developers. When authorized to deliver offensive cyber effects, our technological and operational superiority delivers unparalleled effects against our adversaries' systems."
