British OOB June 1944 - additional formations?

[Imp]

However, I have read that Britain supplied the Boys to Finland and it was used effectively in the Winter War against light Russian tanks. I've also read about light Japanese tanks being KO'd by the Boys

I bet the Finns were impressed with it, definetly atributed to the Boys? there home grown ATR lahiti or something like is good still need several though.
Boys not sure if I have killed anything but damage immobolise yes. Either assaulting with or within a couple of hexes otherwise its just a suppresor IMHO.
Finns Lahiti is a diffrent mater kills very rare with one hit but have killed 3 armour with it possibly 4 with consecutive damage. T-26s T-60s AC etc
