the CIA documents is protection on the frontal arc. LOS thickness from 0 degrees front will be higher than CIA numbers on the chins, and equivalent on the gunshield.

Ah yes true. In US protection is always provided for angle of impact 30 deegres from turret/hull longitudinal axis, not at 0 degrees, so protection will differ.

[Damian90]

I think I confirmed that hull front is thicker

 

 

On this photo we can see that anti slip coating pattern is different with additional strip in front just above the edge of the armor, also front lights are moved forward and large space without anti slip coating left behind them, compared to the older prototypes and tank variant

 

Here the old hull anti slip coating and lights placement relative to it is even better visible.

while Challenger 2 is unclear, some sources claim DU was added to it's Dorchester armor, some says Tungsten.

I've come out of lurking and created an account to ask where one could find such sources.

 

Cheers!

The "Armor Scientific" discussion board of www.tank-net.com is a good starting point for searches.

Yeah I recall it was mentioned on TankNet years ago.

Allegedly this source claims that Challenger 2 might use Tungsten as part of it's "Dorchester" armor.
