I dont think any part of the hull is thicker apart from the upper front plate, which is obviously significantly thicker due to the new armour arrays.
However, those six little circular protruding pieces are new, I wonder if they could be used to mount external armour. They could also be part of the fixings for the new internal armour as they seem to align perfectly with its angle.
It would be nice for us to get the more modern Challenger 2 as seen in the first ingame ingame, mostly because it has that applique UFP armour which could probably make it stop most Russian rounds
Hope to see it with either EuroTrophy or Iron Fist-Light Decoupled (IF-LD) for the production variant. The IF-LD would probably be the most effective in-game as seen on the Black Knight compared to the Merkava IVM.
Seems they havent worked out a mounting solution for it, i imagine itll probably end up being on some odd little flaps or something on the turret side/roof
the smoke grenade launchers already need to be connected to the tank’s systems, i feel like mounting it near the smoke launchers would be the least intrusive
