Some very interesting material:
The Panzerknacker, german army manual for close-antitank combat.
Panzerknacker means something like Tank cracker, crasher, is like another word for antitank:
Plate 1:
"Tank Killer: Instructions for Close Combat with Tanks
Leaflet 77/3"
Plate 2:
"You also can crack tanks!
You need vim and presence of mind. Above all superior savvy will prevail.
Think that tanks don't come only where there are paks [anti-tank guns]. Every day it happens that tanks infiltrate somewhere. You also can face suddenly such a coffer ["Kasten" also means box, hutch cabinet]. Anybody, if you are in the rear, if your are in the furthermost trench, you can get into this situation. The tank does not ask, weather you were trained to be tank cracker or something else.
Every body can do this - even you!"
Plate 3:
"A tank every 150 meters.
Over 1500 km.
What many others do daily,
You can do just as easily.
Over 10,000 German soldiers wear the Tank Close Combat Medal [Panzernahkampfabzeichen]. That many knocked-out tanks corresponds to the equipment of 200 Russian tank brigades and the total Russian tank production for a half year.
And all that done with the most primitive means, no less. But these lay in the hands of real men, and that's what it boils down to.
You ask yourself, how is that possible under such unequal conditions? It's quite clear: First off, tanks go after evenly matched opponents: tank, AT gun, and flak. At first they don't pay you any mind. But then, pay attention:
You can kill tanks too!"
Plate 4:
"On the other hand,
Even the strongest tank has weaknesses.
Have you ever attacked alongside tanks? Or ever sat in a tank? You will have noticed right away that the fight between man and tank is so uneven—not at all, because even a tank has its weaknesses!
It sees poorly, poorest of all that which goes on right next to it.
It hears poorly.
It can't defend itself well against you, particularly when you're right next to it.
It's highly dependent on terrain.
You have to know the weaknesses of the tank. You'll find every different production type shown in exact detail in the Tank Close Combat cards (Supplement to Army Manual 469/4) Get them and study them. The first requisite for the tank killer is: know the type. Know the weaknesses. And of course: observe, observe, observe.
(Cannon blind spot = around 7-24m
Small arms blind spot = around 5-9)"
Plate 5:
"Success at tank killing comes
When you know their weaknesses, otherwise not at all.
Overall, note the weaknesses from this sketch. It's only a schematic drawing, though.
(front: hatches, optics, guns and mantlet, turret ring, MG and vision port, running gear, final drive train.
(aft: hatches, turret ring, hatches, running gear)
(side: cannon, mantlet, vision ports, ventilation, running gear, turret ring)
(His coat has worn patches,
And tanks show their weaknesses in the same way!)
There's no basic formula for the positioning of these locations. So, commit to memory the Tank Close Combat and Tank Identification cards.
It's fear that it generates!"
Plate 6:
"Dangers are already half averted,
As soon as we recognize them clearly.
(black bar: "From here here he sees you."
Red dot: "Danger lurks here.)
A tank is definitely not completely defenseless against close attacks. It has pistol ports through which the tanker can shoot with pistols and machine pistols and throw grenades. Aft MG's are also dangerous. You only need to know: where does he see me most easily? Where does danger threaten?
Note: With hand grenades, he can also reach you in the blind spots.
Look out, danger lurks here!"
