That is not an excuse.
Which was completely off the mark by a longshot.
Come on, seriously??!! What's so wrong with drawing comparisons with the models that are considered to be the benchmarks for modern MBT designs all over the world??
Anyhow, since you asked, by taking the internal arrangements of the instruments, the positioning of the crew, and then extrapolating that data with the turret dimension and the size of the GMS, we can safely reach an estimated value between 350-400 mm max for the thickness of the armor section behind the GMS, so we take the median value of 380mm. It could be slightly higher (plausible but not likely) or slightly lower than that but definitely not at the level of Leopard 2A4, that's a mathematical certainty at this point.
The BS models few trolls who posted here as that of Arjun are just fake,,,
And taking a median value based on fake models is,,,,,,, your speciality it seems,,,
SInce you dont even know the sixth grade geometry in "mantlet discussion" ,,,your "scholarly sounding" mathematical certainity is just ,,,,,, funny
