We all focused on the RWS on the ACV. They did something with the "armor" too...

Look at both pics. Tried to get them coming out of the water. Did you notice the difference (besides the turret mounted weapon...don't be a smart ass).

Still don't see it?  Check out this pic of one on land.

Still don't see it?  Geez, you guys aren't paying attention.  Ok.  I'll highlight it for ya.

We were all focused on the RWS but it appears they added what I'm GUESSING is hydrodynamic improvements to the vehicle.

I'm going in that direction because of the mission set.  Sustained land combat is out right?  I was kinda leaning toward maybe a beefed up armor package but .... Hell I don't know.  What do you guys think?
