The SU-85 doesn't need to engage in 50 range and can sight for itself, the JPIV can cloak while having the smallest target size of any vehicle in the game. I compared the StuG III to the Jackson for a reason; they both have very similar armor (one it 140 one is 130).
The Jackson has a turret and superior mobility (60 range as well) to the StuG but less health, really it's a toss up between the two which is more glass and more cannon since one has high alpha and one has very good DPS. But both are meant to be supported by other things and are hard countered by AT guns.
The short gun sherman isn't a class cannon because it's got a turret, very good speed and acceleration and smoke. The T34/76 is just well, uh, not very good lol.
I think we had a little misunderstanding because your definition wasn't at all clear to me. Now that you added to your definition over the last 3 posts it seems clearer. I have taken note and have come up with a check list. Could you let me know if I missed something in there? If it is correct, I'd agree that the jackson and stug qualify as glass cannons according to your definition.
Definition of a glass cannon:
- doesn't have a target size smaller than 20 (elminates some light vehicles and the jp4)
- dies in 4 shots or less (elminates havies, Brummbar and Panther)
- has a speed of 6 or less, unless it is a tank destroyer (eliminates medium tanks)
- cannot spot for itself (eliminates su85)
- doesn't have cloak with vet (eliminates jp4 again)
- doesn't have a turret unless it's a tank destroyer
- has less than 60 range, unless the 10 range difference is compensated by being killed in less than 4 shots
you didn't mention it but I think you'd add this
- is not a m10
