The Challenger 3TD tank has an armor bug, the minimum equivalent thickness of the 30 mm thick rolled armor on both sides above the turret is 10 mm, which is not true, the equivalent armor thickness of the vertical angle should be close to the thickness of the rolled armor, not less than the thickness of the armor, this is a bug, and I found that it is equivalent to the additional rolled armor of 10 mm above the gun root, so I judged that the 30 mm rolled armor here was actually made of 10 mm. Hope it can be verified and fixed soon, thanks.
The 30 mm thickness of the inclined armor in the same position above the Challenger 2 is greater than 30 mm at the angle of inclination, verifying the Challenger 3’s error.
