Challenging the new COIN doctrine

LtC Gian Gentile (who I mentioned earlier here) has an article challenging FM 3-24, also known as General Petraeus' counterinsurgency doctrine. It's started some spirited discussion, in which LtC Gian Gentile has taken part, at the Small Wars Journal forum. I found the thread when I noticed a bunch of hits all coming from a referral at SWJ. Apparently my two earlier posts mentioning LtC Gian Gentile are number two and three on Google. No idea how that happened.
