You seem to be determined to rewrite a bit what is known about modern Western tanks. Well, I stick to what I said. I could refer you to the forums of eSim and have your theories discussed with the guys there. The audience is brimming with former or still active tankers and military members, and several tankers are engaged in the creation of their sim (which is bought by over a dozen Western nations).
I trust their discussions over the past years slightly more than you, sorry.
No personal offence meant. I am juzst not that active over there anymore. Time changed over the years, so did the man.
