Actually the front of this turret is 152mm of armour with several sections of the internal mantlet being another 100mm's (similar to the Challenger in WT however it's still missing a lot of plates...).

That and it is (if facing a target directly) slightly angled at around 15 degrees making it effectively more closer to 160 to 170mm~ everywhere but the vertical middle, making it a more annoying target then a Black Prince with you having to try to shoot for it's internal mantlet frontally between the slit to try and hit the ~100mm area. The sides of the turret isn't 76

[BEFORE POST EDIT: See annotation at the bottom]

The hull is 101mm of armour with 12.7mm of armour right behind it so it is at least on par with the Tiger I's armour with the angled parts being closer to ~120mm effective armour with the current angling calculations roughly and the secondary plate will take some shrapnel away from AP rounds since that's how WT's armour works apparently so using APCR on this would be a nightmare.

This being said, here is where it sits in terms of armour for the hull...

• Churchill mk III (BR 4.0) has weaker hull armour.
  
• Churchill mk VIII (BR 4.7) has stronger hull armour.
  
• Black Prince (BR 6.0) has stronger hull armour.
  
• Centurion (BR 5.7) has stronger hull armour. [however the side armour is so thin you can't angle]
  
• KV-1 ZiS-5 (BR 4.3) has weaker hull armour.
  
• IS-1(IS-85) (BR 5.3) has similar hull armour, thicker at the driver area but is a 'piked' design, can't angle.
  
• Tiger 1 (BR 5.7) slightly weaker hull armour, doesn't have the 12.7mm plate behind.
  
  in terms of turret...
  
  
• Churchill mk III (BR 4.0) has weaker turret armour.
  
• Churchill mk VIII (BR 4.7) has ~slightly weaker turret armour.
  
• Black Prince (BR 6.0) has ~slightly weaker turret armour.
  
• Centurion (BR 5.7) has weaker turret armour.
  
• KV-1 ZiS-5 (BR 4.3) has weaker turret armour.
  
• IS-1(IS-85) (BR 5.3) has weaker turret armour.
  
• Tiger 1 (BR 5.7) has weaker turret armour, however it has a lot of geometry to it that can absorb shots into oblivion which is actually the design reasoning from memory for it to be like that.
  
  It is also armed with the 17pdr and I believe due to the fact it was intended to come out after the Challenger it would receive APDS for two main reasons;
  
  

1. being the fact it would've saw service very late into the war and all other vehicles (besides Tortoise and Avenger) has APDS in it's time period for Britainn.
   
2. the TOG II* was intended to have the heaviest firepower on a turret mount at the time, with some documents claiming it did have a 27pdr mounted before switching back to a 17pdr. While provisioned documents had everything from prototype 75mm "longs" to 37pdr's intended to be mounted. Not that I am asking for a 37pdr TOG (though a 27pdr TOG premium if we get more info won't be bad...) but it's just the general idea that this vehicle is meant to be heavy in firepower.
   
   That being said, the list of British tanks with APDS in ~Rank 3 are...
   
   

• Comet (BR 5.3), 77mm HV.
  
• Challenger (BR 5.3), 17pdr.
  
• Centurion 1 (BR 5.7), 17pdr.
  
• Black Prince (BR 6.0), 17pdr.
  
  Looking at this, we can imagine that with the armour similar to some rank 3 vehicles (Tiger, IS-1, etc) with a cannon that with APDS appears inn a similar BR range as just listed above, we can imagine the tank around BR ~5.3 to ~5.7.
  
  The only cons of the design is speed and size, the size makes it easy to spot especially from air so beware of CAS since UK doesn't have any super SPAA's like other nations (Germany) at the current moment and its speed is quiet slow...
  
  HOWEVER the TOG 2 had several engine tests and/or provisions as well as super chargers from memory able to increase the horsepower up to ~1000 hp, now that isn't too spectacular as we have tanks with far higher, however compared to Rank 3 heavy tanks it would have the highest... not that it would be the fastest mind you due to the tonnage, but it can be faster than the snails pace we had for the pilot version. We can assume that Gaijin would most likely choose the snail pace or one of the engines around 600 hp.
  
  The most likely speed we would see it at if Gaijin doesn't want it to be faster is 13.7 km/h. Not that bad if you are a Black Prince and Tortoise fanatic but it isn't exactly the speed of lightning either...
  
  A huge pro though is the TOG 2 can accelerate quickly, climb steep inclines, can turn quite well even in the thickest of mud, in fact in everything but speed it is considered the most mobile tank of WWII in testing as it is the only tank to pass every test and then extras. So the TOG won't be a fast tank but similar to the Black Prince it'll be hard not to have it go max speed the entire time you are going to battle.
  
  though so should the BP and Churchill and other infantry and cruiser tanks of the British.
  
  *my overall verdict is that I would like to see the Standard TOG II at BR 5.3 to 5.7 British as there is a huge void of heavy tanks both in reality and in WT that would be 'superior to the Churchill VII' but weaker than a Caernarvon to fit in the BR 4.7 to 6.7 gap, a huge problem since UK only has 2 tank lines instead of the 3-4 other nations do. It may not be the easiest tank to drive but I heavily enjoyed the Black Prince and her play style so a similar tank doesn't turn me off!**

  Okay, from my understanding we can have anywhere from 114mm of armour + 12.7mm too 152mm of armour on the hull depending on what TOG II we get in WT as the design has changed a bit from start to end. So the TOG II can end up as a tank with similar to slightly superior armour to the Black Prince instead of what I mentioned before and potentially anywhere between.

  TOG 2 has better armour then known in public domain, with 152mm on the turret front and anywhere between 114mm too 152mm on the hull. though I am leaning on having 114mm. The TOG 2's gun isn't bad and there is a slight chance for a 27pdr armed TOG II. The Tank may be slow but it won't be slowed down as it has good traction, turn time, acceleration, etc.... however we may have the possibility to have a faster TOG II that will go above 13km/h similar to how we have a Tiger II Sla... that or have that as a premium version at .3 BR higher.
  
  EDIT
  
  The driver port area is 6" thick (152mm) and some areas around it, meaning the easiest place to hit that isn't angled will be a geometrical mess of thicknesses with most being 152mm, so it'll be pretty resistant overall to APCR and early German 75mm's.

  Mostly a combination of the The Tanks of TOG: The work, designs, and tanks of the Special Vehicle Development Committee in World War II, a book written by Andrew Hills recently and me talking to Andrew Hills myself of which I have seen more primary documents scanned of the TOG then I have seen for any other tank. World of Tanks (surprisingly enough) butchered the TOG II, and David Fletcher does show a strong personal bias against the Tank which is why tank designs like the TOG 3 and 4, the TD's, etc of the TOG isn't heard of yet in the major public. It would be obvious to anyone who has heard him talk about the TOG when you realize the tank has been in development for a very long time with new innovations every so and so to the point that some produced British tanks borrowed them and the fact David has more praise for the Valiant over the TOG...
  
  If you want I can start linking the books sources themselves for certain sections though keep in mind that book is a few hundred pages long and I am not exactly the fastest reader out there.
