The USMC has made some errors along the way; Osprey comes to mind. Why did the USMC not just buy Black Hawks and forgotten about the whole MV-22 deal. I think the A-10's are still a fantastic CAS platform. I like to see a life span report at the 10 year mark on the Mv-22. The only thing that spears the USMC from the contracting mess is the fact that the USMC does not do acquisition on a level like Army,Airforce or Navy. But your right, the culture has always been geared towards the survivability of the trigger puller. That is really where is starts and stops.
Many people have forgotten what it really means to serve. Retiring with a paycheck and the job across the hall at the Pentagon seems to be the thing. You know when 0-4's go to the Pentagon, they loose their spine! Atleast it is preserved until they finish their tour.
If change must take place, people like you have to stay in to fix the mess otherwise the jackasses will stay and rise to the top and further mess things up. It has always been that way, the only difference is that their percentages have increased.
