As with most things in life, the truth is probably between the extremes. There are professional military critics out there, and not all on the left. While I enjoy some articles on G2, you have to have some skepticism for the skeptics. The "cheap hawks" have shadowed the military since the 80s. Back then, they would have preferred us to buy small-deck, British-style aircraft carriers. They wanted us to buy the F-20 Tigershark (F-5 variant) over the F-16. The thought stealth was a waste of money. The Maverick missile was derided as a failure, as were the B-1 and the Bradley IFV. The Bradley was supposed to be a sitting duck for the enemy. It was the star of as many 60 Minutes segments as the V22. You'll remember all the smoking Bradleys in Gulf I and II--what? You don't remember? If we'd followed their lead, we'd have Russian-style armed forces with a whole lot of cheap, simple, P.O.S. gear.
A rock is the simplest and most reliable weapon there is. However, I'd still bet on the guy with the M-16, even if it jams every so often. Even if the Osprey doesn't do 2100NM inland as advertised, it'll still go a crapload further and faster than a H-60.
