Blast from the past. FMC's LVT00 Concept.

How long has the Marine Corps been planning on replacing the AAV?  How about since the early 80's!

I was surfing the web and ran across the above advertisement from FMC (later United Defence and after that BAE) that shows a concept LVT00.

I'm digging for more info as we speak, but it looks like its just an evolutionary AAV.  More to come...I hope.
