I know I'm digging up an old chestnut here and it really seems quite minor, but here goes.
As evidence has been found indicating some Canadian use of the Thompson M1A1 in Normandy, it's justifiable that they have it for their NCO kit. However, I've never been able to find any concrete evidence that British units were by and large issued with Thompsons rather than Stens anywhere in Normandy - Italy and other 'secondary fronts' yes, but on D-Day and later I've never seen a Brit with a Thompson. It always bugged me that British officers had Thompsons in FH1, and I'm again puzzled as to why they have them in FH2.
But please, if there is evidence that supports British (not Canadian) use of the Thompson, show me it. It'd put my mind at rest every time I look at the British spawn screen (which, IMO, is spoiled somewhat by the harshly different metal and wood colours on the M1A1 after the similarly coloured No4s, PIAT, Bren and Sten guns).
