Possibly important to note the timing of this admission right on the heels of the announcement of our defense minister that she wants to build a 'cyber' division in the army with 13500 people working there. Thats almost 10% of our armed forces. I could only find decent reporting about this in german: http://www.tagesspiegel.de/politik/plaene-der-verteidigungsm...
The challenges of information technology w.r.t. warfare are fundamentally different from usual war tactics. You can't solve them by throwing lots of personel or big guns at them. If midst-fight your equipment or infrastructure fails because of security flaws, it's not because there's no personel to deal with it (for that it's already too late): it's because its designers failed at the drawing board.
It'd be better they concentrated on quality instead of quantity and the resignative "anything can be hacked" myth a lot of popular media is putting forward, as if information technology operated according to the same rules the physical battlefield does. These analogies only go so far...
(of course the same applies to non-military contexts as well)
