Nope, the bulk are me only. Occasionally I will turret the bigger stuff and another player will finish them off because the smoke gives them away. Panzers are easy, anywhere on top tends to work. T-34s needs to be the top of the turret which is a small target, if you smoke the turret then a 2nd shot finishes it off (include the /85). Panthers and Tigers are the same. The M4 is the hardest work due to it's small turret.The roof armour on the turret of the tiger 1 is 25mm. The NS-37 is rated to 30mm at 500m. Yes it is a tricky shot, but it can be done. But you are quite wrong to claim it does not have the killing power. I can absolutely assure you the Tiger kill was all by myself (no friendly tanks close to the tiger at the time).
How many shells? I would usually fly a Hurricane IID in this instance where I know that 40MM AP will tear right through the top turrets. I can nail a T-34/85 or an M4 or Panther, but the Mighty Tiger 1 requires multiple top hits with the 40MM AP to crack. The Tiger 2 just laughs at me...
Vulcan, if you can kill with the yak you can easily use the stuka since ymir doesn't require such steep angles. T34s under tree cover or on the move must be really tough with a yak.The real issue is surviving with an air threat!
