Great concept!, I also remember a doco about Red Adair and his crew's exploits in the war's aftermath tackling those fires, man! talk about balls the size of dump trucks for all the guys who'd capped the wells
The hardsurface modelling is top notch finesse considering the overall complexity of your project, much respect by the way porting in-engine really illustrates the time and effort involved.
A small crit though, (...sorry possibly being too nit-picky) by assessing the earlier updates what is noticeable from my POV are the dimensions of the track pin bushings, link tread and nuts seem to be slightly out of proportion. I've a military background when a young man waaay back in the day, whilst on assignment I recall details when seconded to a tank museum working on a captured T54/55 exhibit alongside jogging the ol' memory via google'd images of this T series variant as well.
Anyways duly bookmarked, will look forward seeing further progress.
