Interesting. M3 Halftracks sent to UK/USSR: 2 each?
More like Super Special Weapons Regiment.
Also I should point out that apparently some of the Soviet skins cover the M3 halftrack but because it's so ahistorical I'd vote against it anyway
The WC-51 would definitely be much more historically accurate as a weapons carrier for the Brits. Other options would be the M3A1 Scout Car or M5A1 Halftrack, but definitely not the M3.
