Killing infantry in both games is about the same - as the code is rather similar. MBT is usually easuer (the tanks generally have 10cm+ guns).
You do not yet have the new EXE, which fixes a few problems with over-effective splash damage as yet (esp to armour). It also fixes some points about close range fire which needed tweaking (to allow for training and supression status) - you should be able to close in the new version and take 25-40% to-hit, more chance of close range panic (if firer supressed and low training). Less 85+% to-hit at 1 hex, especially if you dropped some arty on the defenders prior to attempting to close.
I will probably go over the MBT code and port in any requred fixes sometime this summer. (I need to get myself up to full speed on Java before September as I am off to University as a
very mature sudent, converting my HND to an honours degree. Does not look daunting as it is just a rewrite of C++). BSc (Hons) Computing (Games Development) at University of Abertay, Dundee if anyone is interested
