Hehe...yes there was even occasion where tank was forced to abandon with mud. Yes you heard right mud. One überfinn seemingly out of his mind attacked KV-1 heavy tank with mud in his hands. He then climbed over it and rubbed mud on vision slits which completely blinded tank. After some time crew realized they had no choice but to abandon vehicle since it's rather hard to drive anywhere without seeing a thing. I think this mud fellow earned mannerheim cross for this action. And finns got brand new KV tank for their own use.

Also there was numerous occasions where finns pushed logs between roadwheels of russian tanks immobilizing them. :D

>>suffice it to say that the ballistics in AH are in "some aspects" slightly goofy.

Anyhoo......heres hoping for a more challenging guns solution somewhere down the road <<


Hear Hear! Well said Yeager.

ergRTC:

The armor was proof against 30cal/.303 class weapons and provided some protection against .50s (i.e. high angle shots or rounds sufficiently slowed or destabilized by passing through other aircraft elements).  Some protection is better than no protection.

Hooligan, are u sure that a 13Kg panel of 12mm armour for the head was there to stop 30cals in a 1944 190A8? :eek:

Mandoble I know you are not a native English speaker but what part of "provided some protection against .50s" is confusing you?

The seat armour had 5mm and this would be intended to provide some protection against 50". A hit in the seat would had passed through some other parts of the plane. But not in the head, these 12mm of armour should provide total protection or just none, "some" protection for the head is like no protection at all.

Mandoble:

Your reading comprehension problems are breathtaking.  I suggest you reread what I originally wrote.  .50 AP rounds could penetrate over 12 mm of armor plate at 600 meters.

He was stoped , and shooting out the right side of the tank. He took out my track, but thats all he could do, i on the other hand blew him up with 2 hits. He comes on the radio complaining how the damage model is porked because he hit me quite a few times and couldn't kill me. Well guys this is what pure realism produces, his shots were all hitting in my strongest armor, mine hit him on his side armor. Mine penatrated, his did not.

Now look at an m3, if you put an ap round into the side of the truck, odds are in real life it will just put a hole in the sheet metal and continue on.

Hello Hitech.
He should have penetrated your front turret easily from 1800yards.(Numbers above)
If he was hitting your front hull it would be just on edge of possible penetration. (75mm gun of Pz-IV penetrates 91mm at 0degrees at 2000m.)
But ofcourse trajectory of shell makes 90degree hit angle not likely. Some round might penetrate...some might not. If round just barely penetrates it wouldn't easily destroy tank tho. Armor flaking inside would possibly injure crew member(s) or do just nothing.

Yes at optimum angle. So lets guess 400-500m for likely penetration from 6 a clock in aircombat until Tony(he must have some numbers for .50cal) comes here.

5mm might be enough after rounds tubling trough fuselage. Direct hit to 5mm plate would go through to 1000m atleast. But rounds go all but tip ahead and straight after hitting something.

I think i've seen 2 types of head armors in FW190. Other is like angled tube(which seems very good for ricocheting rounds away) other is this 12mm plate youre talking about. I think angled was to have better protection against .50cals since 12mm doesnt seem enough.

Also , a lot of the armor up front would not cause a 0 deg hit most of it is sloped.

Actually those are the same rounds (M2 AP and M8 AP/I) that were commonly used in WWII.  Modern rounds like M903 SLAP and M140 Raufoss rounds have significantly better penetration.

Hooligan,  I suggest you reread what I originally wrote too, penetrating NOT EQUAL damaging what is behind. Hey, I have english comprehension problems being spanish, but your case is much more alarming :D

Just to add a point about your link, it states that it was MAXIMUM penetration, I suppose also for optimum conditions, but, in the case of traveling these 12mm, what is the resulting deformation and kinetic E loose of these projectiles?
