Thanks to Costas TT for the eagle eyes!
The above is a screen cap of the vehicle that Costas TT picked up on and I missed from Modern Day Marine. It looks like General Dynamics gave the LAV the "high tech demonstrator"/'LAV 5 treatment.
The other thing of interest is that turret. It looks like a modernized AAV setup with the addition of optics and anti-tank missiles.
Interesting vehicle. General Dynamics is still on the grind.
