Looks like Tiger v T34.

P.S. I actually helped with research and testing during the early development of that one. I had been involved with gaining the rights for a small team of enthusiasts to continue development of the original Panzer Elite, and that led to an invitation by G5 for me to give them some input on this one. G5 ran out of development time and money, so they never really finished implementing all the things we (Alpha Testers) had suggested would make this a great sim. I moved on from tanks to working on enhancing CFS3, but my friend Aldo is still plugging away at Panzer Elite.
