After looking at some of the Aggressor documents, I got curious what was being worked on around the end of World War 2, and one of the more interesting vehicles is the T30 heavy tank. According to R. P. Hunnicutt's Firepower it was actually slightly heavier than the T28 superheavy tank, despite only having around half the armor. It was that heavy because instead of the T28's 105mm gun, the T30 mounted a 155mm L/41 monster. It was intended to take on a King Tiger or Jagdtiger (or IS-2) with odds in its favor. Muzzle velocity was somewhat lethargic at only 700 meters/second, but 155mm of HEAT was found to have an impressive effect on pretty much anything it hit.

The gun has an extremely low rate of fire because its two-part ammunition is still heavy and difficult to handle, with the shell being almost 100 pounds without the powder charge. The T30E1 added loader assist systems (a power rammer and systems to align the gun with the rammer and return it to battery), but not a full autoloader, which would improve Rld to 2.
