Totally out of the blue they came up with a medium tracked vehicle to add to their portfolio based on the Stryker. I'm trying to read tea leaves here but could we be looking at a strategy to get the Marine Corps Amphibious Combat Vehicle and Marine Personnel Carrier contracts?
What I mean by this is that they're playing the price shootout game. They leverage the massive Army buy by basing a family of vehicles off one variant.
Imagine this...the Tracked Stryker along (that will have further modifications like the driver moved further back, the vehicle widened and larger tracks placed on it) wins the Army's AMPV contest, with a few more modifications its made to swim and because of the Army's buy they'll be able to price compete on the Amphibious Combat Vehicle and with the work done to make the Amphibious Combat Vehicle they simply revert to wheels and enter the Marine Personnel Carrier Program with the same basic hull that swims.
I could easily be wrong but it makes manufacturing and design sense.
