i couldnt find the film, as i forgot what it was named (film ##) and i have over 325+ films so its not really going to be any fun trying to search for it, so i have some soft spots on the top of the tiger 2 that ive outlined in red. (top view)

when i did the turret, you always want to aim at the back side of it. thats where the ammo is held and if you hit the front, well, your just going to turret him. also, you can always aim for the drivers seat. for some reason if your driver dies your tank is going to hell. and, the most popular choice of all....the engine block! basically keeps the tiger immoble while the guys on the ground can work around it and kill him. hope this helps!
