M1A2 Jagdbrams Tank Destroyer

Single day project that started (and ended) as as joke photobashing an American Abrams MBT into the ridiculous German WW2 case-mate vehicles such as the Jagdpanther and Jagdtiger.

After some feedback additional alternative models developed, and despite the short nature of the project I'm trying to do a better job documenting personal work so there is a resource page.

Minor notes since there is not a spec page:
.
Gun would likely be 140MM and would for internal space + the weight of the ammo require an auto-loader configuration. If the entire vehicle was enlarged such as in the third picture then there could be the possibility of a 1-2 person loader crew.
.
Weight for basic version and with the M1a2 Sep v3 Trophy system would be 3-5 extra metric tons, offset by weight reduction from removing the turret.
