Right We're all aware that those huge slabs of Chobahm are good at stopping RPG-7's, linked to the WR's surviabilty makes them Quite a good vehicle... HOWEVER:
A closer look:
That looks Like Extra Slat armour on over the Chobahm armour, it looks to be placed mainly to protect the area's that the Chobham doesn't cover. So maybe even bigger Anti-heat value on the sides and front of the WR in the next update?
Edit: looking closer, it seems to be on the turret as well.

I've also read that the WR fleet is getting a Balistic Computer upgrade, and I'm still waiting to find out details.
