like the guy who comment above me we need the m4 sherman not the firefly, and dont perk the sherman and raise the price on the firefly, because they couldent 1 shot kill tigers from the front! { i have had this happen to me many times } and the sherman has a smaller gun { same mm then the firefly but its not a 17 pounder }
If you don't think the Firefly was capable of front shot kills on a Tiger, you should read the history of the Firefly and some AAR reports. That 17 pouner main gun was a beast.
ack-ack
