I am pretty sure this is the right place to post this in the forums.
Anyway, I came across this book that provides a lot of information about modern vehicles. The book is "Modern Tanks"by Mikhail Baryantinskiy. It is in Russian, so you will need to translate it: Modern Tanks by Mikhail Baryantinskiy, 2013.pdf | DocDroid
I hope this document will help people create bug reports to ensure a historically accurate game, or at least point them in the right direction.
