Systems rule .....BUT Systems Engineering can get you into a lot of trouble when you try to apply Engineering against Biology.
Mankind has always done that, remember the 6 Million Dollar Man

That is closer to reality everyday, and now we're able to map genes and even execute genetic engineering. Nanotechnology and artificial intelligence will take into a brave new world that could in fact dominate biological systems. We missed it, but our grand kids may be turn out to be super warriors (cyborg types), or they may all get killed do to the development a superinfection that is created in a lab in someone' garage.

Tying it back to the thread, there is a serious danger of missing the boat when you tie your future doctrine and force structure based on the last 10 years of warfare.
