That should show you, or more realistically show the unbiased reader, that:
1.) Range
2.) Angle location of impact
3.) Weapon used
4.) Time of impact
have absolutely no bearing on a survey aimed solely at finding THE AVERAGE number of hits needed to knock out a tank/make it burn.
I have to disagree with a few of these.
3) Weapon Used
Just because a weapon hits a tank does not mean that weapon is capable of destroying it. By your method, if a Tiger was hit 9 times by a 20mm, and once by a 150mm, then it took an average of 10 hits to destroy it - which abviously is not the case.
4) Time of Impact
Counting the number of hits also assumes that the tank was not destroyed until the final shot when it actually could have been the very first shot.
Why stop at 20mm? Why not count .303 strikes as well?
The smallest A/T gun was a 6pdr And the shot count only counted 6pdr, 75mm, 3 inch and 17pdr. 20mm or 150mm (which would be H.E ) were not tabulatedand and thus do not skew the figures in any way.
I know of no tank destroyed by 150mm anyway but if you have information on such a hit (or how frequently such a strike occurred) please share it with us.
That line or reasoning would REDUCE the number of hits and make the German tanks MORE VULNERABLE. The method used by the OR people thus is the WORST POSSIBLE CASE SCENARIO for German tank vulnerability.
Did you really mean to say that a Tiger did not need 4+ hits to be knocked out??
I was mearly throwing out 2 extreme calibres to illustrate my point (150mm were not only HE). I am curious however exactly how could they tell which calibre left marks/holes? A 37mm fired at point blank range (which was not included in the study) could potentially leave a mark simiular to a 75mm fired at 1,830m (which would have been included).
It would not make the tank(s) any more or less vulnerable as reality is reality, however it could change the interpretation of the data which is exactly what you want.
As a person who uses statistics on a daily basis for work, I can tell you it could scew the results whic is exactly what you don't want. I can also tell you studies made in an uncotrolled environment can lead to bad data. But you have my curiosity up, ss there a link to this study?
Viking,
So all in all the statistic is useless, and so for very obvious reasons.
. There's even an incident in which one got hit 246 times, yet it kept on fighting!
M_kenny doesn't seem to understand that a statistic which doesn't take into account the range of the engagement, angle of impact, location of impact and type of attacking weapon is completely useless.
The ONLY thing a survey of hits penetrations on enemy friendly material can be used for is to assess in how many of the incidents the attacks were from the front, sides or rear.
And unless there's just one penetration then there's most often no way of fidning out which "hit" knocked out or lit up the tank.
So while the material presented by MK does tend to corroborate that the numbers of hits needed to knock out a Tiger was not ten (and this already and automatically takes into account the variable of range etc) I dont see how it can be of benefit to the frontline forces unless the circumstances of each engagement are known.
I dont see such a survey as being useless....the engagement ranges (and all the other factors you mention) are a variable that contributes to the outcomes, and hence the average number of hits needed to knock out the tank. Thats what OR does, it is a "results driven" statistical analysis.
If indeed, the average number of hits needed to knock out a German tank was about ten, as you say, then one would expect to see a lot of German wrecked tanks with "about ten hits" on them. If we cant find that, then the original paramnreter has to be interrogated. If it was "about ten" needed to knock out a Tiger, why cant we find the evidence of that????
One explanation that might partially answer the issue is that many German tanks were not casualties from anti-tank fire.....perhaps they were knocked out because they ran out of fuel, perhaps some simply broke down, and there was not time to fix them....perhaps the tank was cornered and ran out of ammunition.....there are other variables at play that might skew the dataset....however, to try and say that the variable within the actual combat loss dataset is to fail to understand how OR works.
As an example (hypothetical....I am just trying to explain how the OR results might work)....say there are two units in the field that are exactly identical, except that one tends to engage Tigers at 1000 metres, and the the other at 200. The first takes, on average 10 hits to kill the Tiger, but loses 5 tanks in doing this, and for every enemy tank engaged, 5 escape ....The second unit only takes 2 hits to kill the Tigers, on average, but its loss rate is say 7 tanks to kill the tiger, however in this case for every 5 tanks engaged, 2 are destroyed.
Breaking this down it should be clear that engaging at 200m is better than engaging at 1000 even though the shorter range incurs a higher casualty rate for the friendly units. For a 40% increase in ones own casualties, one achieves a 100% increase in lethality of your attacks. For the allies, if these hypothetical figures were correct, the engagement advisory to be sent out to the field formations should be to close to 200 metres to engage the tigers.
So while the material presented by MK does tend to corroborate that the numbers of hits needed to knock out a Tiger was not ten (and this already and automatically takes into account the variable of range etc) I dont see how it can be of benefit to the frontline forces unless the circumstances of each engagement are known.
Lets just be clear that I never claimed that it on average took 10 hits to knock out any tank, that is just another one of m_kenny's fabrications.
Take for example all the times that Allied tankers in vain spended as much as 10 rounds at a German tank only to observe all their rounds just bounce off German armour and then be blown to smithereens by the first return shot fired. Such instances could never be recorded in a statistic like that as there was no'one left to record it. Only the German could record that he'd used a single shot to knock out the Sherman, while the poor guys in the sherman were likely all dead and didn't live to tell how they expended maybe 10 shots or more in vain on the German tank.
If you honestly believe that it one average took 4.2 hits to KO a Tiger then I say you lack even a basic sense of logic, esp. seeing that Tigers often were hit many times during battle to no effect. There's even an incident in which one got hit 246 times, yet it kept on fighting!
Is it or is it not true, that overall Panthers and Tigers were better designed than the average allied tank? Did they or did they not for the most part have better armor and better armament? Just a question...
I have posted the contents of this report may times on a number of Forums and it generates little heat.
Not one person has made a claim it used faulty methodology
However whenever I post the same type of report that has data as to the flammability or mortality rate for German tanks I always get at least one reply that casts doubts as to the authority, methodology or conclusion. I wonder why?
