US Tech Tree Changes And Improvements

MrVic: Actually the added plates were retro fitted and plates cut and attached at the production plant. The panther glacias was one of the versions(tho was a theater change). Cut plates were also used. The addition of the plating was overseen by eng and standard plating was designed and improved and applied.
It wasn't pretty but was a approved design change.
The improved plating brought it's armor on the hull much higher the the t32 turret slightly less then t32. Also the overall size was much smaller then the t32. Until you scale compare them it's hard to see
Also their are a number of 90mm versions tested and a few combat tested
