Mr Noritake,
My apologies to you if I appeared rude to you. That's not my style.
Yes, ADGEs are vulnerable, too, or at least can be, which is a point I make in my post. However, the levels of redundancy that exist and the resilience of the mission-critical components heavily, heavily favour the networked-enabled, cross-environment combattant. Even Sun Tzu (who didn't do a QWI course, as far as I know) would have appreciated this. Remind me, when did he die?
