Should be perked.
Either that, or no perked tanks.
Any fool can take up a Ju87G and go crashing into a nearby tank guns blazing.
People already do things like clusterbomb the entire vicinity of the tank at 1k alt, with 42,000lbs of ordnance raining down from Lanc formations - just to knock one tank down.
What'd they do if they were given a much more effective weapon that drills 100mms of tank armour upon impact? Who needs to practice GV strafing in Hurri2Ds or Il2s? Learn to aim vital spots or set up strafing angles and bearings? No need for such things. Up that flying twin-37mm tungsten core shell shooter and hit it anywhere at close distance, and 100mm penetration guaranteed.
The tanks would be wiped from the face of the MA earth, and once more the GV aspect of the game would go totally stale. Everybody would up Osties exclusively - just like the old days when any strafing gun would disable or kill tanks easily. The end of the whole ground war, armoured assault, tank-blitz part of the game.
