Mc2 I’m just gonna day this now, you were super, very very off. The Sdkfz 186, most commonly referred to as the Jagdtiger, was a tank destroyer that was originally meant to be armed with a 120 mm cannon, but since supplies were low, it was armed with a “mere” 88 mm, which was still a deadly weapon to many tanks.
The Panzerkampfwagen VI Ausf B, most notoriously known as the King Tiger, was essentially a super beefed up version of the Tiger. It was armed with an 88 mm, and had over 10 mm of armor. But it has numerous mechanical problems, and fuel was scarce, as it was built near the end of 1944, but it consumed over 50 gallons every 5 meters. Very little were built, and those that were built were usually abandoned once they ran out of fuel, or used as stationary turrets.
(BTW, I’m a little bit of a military history nerd, mainly in tanks and other armored fighting vehicles. I use this website: http://www.tanks-encyclopedia.com to find most of what I know today. The authors post new articles constantly, and there are hundreds of articles. I’ve read all of them myself [yes, I know, I’m a military nerd.]. Perhaps you could use it to be a little more historically accurate.)
