While playing with my KV-2 with the TBU plugged, I realize that I can only fire the MG about once every 9 seconds, which of course would make sense since it would be classifies as a heavy tanks. While firing my DBU equipped Tiger 1 at my KV, while the Tiger would fire more often, the KV would only register a hit only after 9 seconds from the last hit from the Tiger.

As I’m looking to expand my little army, I’m looking at some medium sized tanks, but there are some German and Russians armor that has me confused as what class they would be. What classifies a medium from a heavy, armor thickness, MG, combination of both?

T-34/85
SU-100
Panther
Jagpanther

Are then any others out there are different then what they seem.
