High Tech has most of the small arms required. Using those converting the rest shouldn't be too difficult. High tech also has a Sherman and I think a Panzer 4, which for the purposes of North West Europe 1944 is all you really need, and gives further guidance if you were looking to do a conversion (ie, ok, a Sherman looks like this in 3e and this in 4e, so maybe a t-34 should look like this in 4e).
