good 1.0/1.3 options
M20 RR has about 100mm of penetration, so on the M3A1 I would argue a BR of 1.7-2.0 would be more appropriate, as a bit of a sidegrade to something like the AS 42/47.
i was more talking about the ones with just a 50 cal
Im just imagining how insanely OP this would be at like 1.7 or something lol, the true heavy tank of the Pacific. Really great find man, well done!
Unfortunately when it comes to actual heavy tanks, there are basically zero options I could find for ASEAN; as while there were Valentines (which could perhaps one day be redesignated as a heavy due to being infantry tanks) used in Burma from 1942-43, it seems that Myanmar only ever got its hands on a few Bridgelayers, and I doubt they were captured WW2 units like the Shermans and Stuarts.
And speaking of the modified Sherman above, I wonder if the answer is inside the “Gallery of the Office of the Directorate of the Armored Corps” room in the Defense Services museum, as that’s where the image originates from. Not like I’m really able to check it out myself.
