This is another sad example of Marine Corps thinking. Remember their current motto: "230 years of tradition undisturbed by progress." I'm so proud to see that my beloved Marine Corps will never change. Remember that they were the only purchasers of the M-103 Heavy Tank. An amphibious force with a tank that couldn't be transported on anything except a cargo ship makes a lot of sense when you think about it. Two piece 120mm round not used by any other US AFV, you get the idea. Actually, there is something else about this that may be indicative of a much more serious problem. Notice they say that the Growler needs to be modified to fit into an OV-22? Now I may be more paranoid than I think, but I seem to remember, in 1984, being able to load two M-151s into a CH-53D without any preparation other than folding up the troops seats in the helo. If an M-151 needs to be modified to fit into an V-22, does that mean that the Osprey's cargo compartment is significantly different from the CH-53's? If so, what other equipment will need to be modified to fit. Remember that the CH-53 cargo compartment was dsigned around the vehicles/cargo it would need to carry.
