1) Su76 has 60 range, Stug has 50 range.
What are health and armor values again?
2) Penetration values:
Su-76 (0/30/60) 200/190/180
Stug (0/25/50) 200/185/170
What are allied meds armor stats and what are axis meds armor stats and average armor?
3) Speed: Can't be bothered, are you crazy Allied fanboys really going to claim that the Su76 doesn't have high acceleration/speed values?
.3 Speed Advantage
.2 acceleration Advantage
allied tanks may be slightly faster, but stug is actually able to survive frontal cqc engageemnt
4) You claim that Su76 "can't kite at all". I'm pretty sure at least a thousand players have proven you wrong. Or maybe you don't know what kiting is.
To kite you need LOS, which so76 does not have on ist own and if you use spotter, stug can do the same.
With 60 range, you shoot first. Then you pull back, which is really easy to do using the reverse button/hotkey. Assuming it's not one of those maps where a small branch can mess up vehicle pathing, you can easily get 2 shots off without exposing yourself to counter-fire. In any case, most players will be too cautious to dive deep into your territory with a weakened vehicle because any reasonable SU player will have mines/Cons/Guards.
Everyone will pull away from poking td, stug does the same, difference is if you hit once with stug, you only need 3 more shot to finish med, if you hit twice with su76, you still Need 4 more accurate shots.
And if sov Player will have mines cons or guards, so will axis Player have grens, PGs and tellers.
You can kite even with slow vehicles like the su85. Kiting is basically about using your superior range to force enemies to chase/commit to diving you. Even rank 500 players are doing reasonably well, so I find it preposterous that you don't understand this concept.
No, you cant because you are not mobile enough and DPS is too low in that particular case youll be chased down and circled.
If there is inf to protect, then there is inf to protect stug as well.
Your comment about "shooting on the move" is also pretty ridiculous and shows once again how you know nothing about the game. Given the 50% penalty for shooting on the move, most decent players will shoot, reverse, press "Stop" hotkey, and shoot again.
StuG have higher accuracy, lower scatter, MUCH damage(Needs 4 shots vs med, when su76 Needs 6, 7 at vet), MUCH higher durability.
If you do the stop trick, you arent going to escape or kite anything, there is a reason why its used only by med tanks against infantry or other tanks which are far away.
