I'm not going to re-hash the bug in detail but it's there & you can kill a tiger with a jeep. ( so an M-8 should work as well )
I will add this though, I read somewhere when I was a kid of a Stuart light tank killing a Tiger with 37MM AP or HE ( don't remember which ) I'm sure he had to have been at optimal range for maximum velocity & kinetic energy, & I'm sure he hit a "sweet spot" like a hatch or something. It may have even been the WWII equivalent of an urban legend.
One of my uncles ( my granny had 13 kids mostly boys who served in WWII & Korea ) who was in Korea said he had talked to some fellow marines who were tankers & there was a rumor among the tank crews of a Chinese sniper who would fire down the barrel of a tank when the breech was open & hit the HE shell to kill the crew.
Now-now....settle down, before you fire off your flames I just want to add I don't believe any such thing ever happened. I wasn't there & have no idea, I know the snipers had everyone worried all the time, & apparently even the tank crews got in on the paranoia.
I just mention this in passing because of pride, I had a great uncle in the Pacific in WWII who won two bronze stars & a silver star for bravery. What I really liked about that guy was he didn't clam up when you asked him about his experiences; he would talk for hours!:aok
