Another thing that some desk jockey thinks up that can only see problems in the future.
I can see it now, an entire battalion lost because of ONE enemy missile. That's calling for much worse outcries than those over a squad lost because of one AAV hit by an IED.
Methinks that this wouldn't be a "first wave" vehicle. That place is reserved for helos and AAV's. This would be for follow on forces/support, much like the LCAC - only larger.
An AAV being hit by an IED illustrates that the Marine Corps is making due with what they have, for what is essentially the Army's core competency. AAV's are designed for amphibious assault, not occupation. Our job is to hit the beach, fight with amazing tenacity, take large amounts of casualties, and get a foothold for the Army to come in with their huge numbers & support.
As is always the case, the Marine Corps will do what it is asked to do... Hence the reason you can say "AAV hit by an IED". However, if we still focus on our core competency (amphibious assault), then yes, this vehicle could have it's place...
