Once they had found the tank (usually fingered by intel), they'd enter the town from different directions
The key the whole deal was figuring out where the Tiger was before they figured out they were being hunted
The tanks would then separate into one group of three and another of two.
The group of three was supposed to drive around fire the odd shot, and back the Tiger into a wall
As the Allies had no weapons that could destroy the front and side Armour of a Tigers, this was a logical move for the Germans
Over the radios, the three tanks would let the other two tanks where the tiger was. They would sneak around the back of the tiger and line up side-by side with apartment buildings between them and the Tiger. The first tank shot a hole in the wall, hopefully revealing the back of the tiger. The other tank would be ready to fire a fatal shot at the back of the tiger.
Highly skilled, highly dangerous, and very lucky if it works.
