It was brought up for its ability to destroy German tanks, though. The 122 mm. D25T was far more capable against German tanks, because of its better armour penetration.
I've always assumed all those years that it means Armored Figthing Vehicle if I was wrong , I'm going to Know real soon
No, you are quite right. See Cholbert's post above. His nationality didn't matter as much as the weapon he was using, and by the end of the war as I already pointed out the Allies had plenty of weapons capable of doing the trick. Some of these were quite common, such as the 6pdr, 17pdr and 76mm guns (provided that APDS or HVAP rounds were available), the Bazooka, the 90mm gun and any kind of heavy artillery.
All that it took was a sock with a high-explosive material (dunno which one) covered in axel grease - a 'sticky bomb'. (saw it in Saving Private Ryan, where they used it on a Tiger to knock of its tread)
Yes, but if tanks are used with appropriate infantry support then enemy infantry will not be allowed to get close enough to use sticky bombs or Molotov cocktails. In practice this sort of thing will only work in urban or otherwise constricted ground.
