On Track to the FV215b Historic Discussion

Major_Rampage: Howdy Tankers!   As you know we are currently On Track to The FV215b.  While you are On Track you might also find our On Track Premium Shop Bundles helpful.   I know we have some amazing history buffs here in the NA World of Tanks community.  I have seen you folks pull out seldom know fact about tanks.     Does anyone have any interesting historic facts or stories they would  like to share about the tanks involved in our current On Track to the FV215b?     Note:  This is a strictly moderated thread.
