A fix of the American TD lineup

Okay, so I know this is going to sound a bit strange to some people, but I found myself somewhat confused by the designated lineup of the American using nations Tank Destroyers, which currently goes as follows:

Level 1: M3 Gun Motor Carriage

Level 2: M10 Wolverine

Level 3: Achilles

Level 4: M18 Hellcat

Level 5: M36 Jackson

Now, my primary beef is with the fact that you go from a GMC (Gun Motor Carriage), to 2 Tank Destroyers, to a Light Tank Destroyer (Hellcat), and back to a regular. Besides this fact is the issue of weaponry. The M18 Hellcat was outfitted with a 76mm cannon, whilst the M10 Wolverine utilitzed the 3in M1918, until the last 300 models were outfitted with the same 76mm as the Sherman. Furthermore, the Achilles has a superior firepower compared to either the M18 or the Wolverine, as the Brits mounted a 17pdr (76.2mm) cannon on it, which is the same weapon that they mounted on the infamous Sherman Firefly.

So, I would like to request a quick change to the following list:

Level 1: M3 Gun Motor Carriage

Level 2: M18 Hellcat

Level 3: M10 Wolverine

Level 4: Achilles

Level 5: M36 Jackson

Thank you for reading.
