I never doubted you thought that.
I live in relatively open terrain, but even here, relatively small undulations can provide many opportunities for cover and concealment*. Even with the current terrain, obviously a lot of play is about positioning yourself to maximise the usefulness of your field of fire whilst denying the enemy the ability to concentrate direct fire on you. Here you could see fro miles and miles in lots of places by cresting a hill, but you had better be quick about it because you would have everything but the kitchen sink thrown at you in short order. It also means that tanks with flat shooting guns and primitive/non-existent FCS like the T-62 become a force to be reckoned with vs far later and more sophisticated vehicles, particularly were they can enfilade or ambush. One thing I am looking forward to very much is that the terrain will make infantry much more survivable, particularly if player controlled - you will be able to readily duck behind solid cover from which you can sneak/run to an alternate position before indirect fire arrives. Yes, timed airburst and, to a lesser extent AHEAD type ammo options will make this less viable, but in rolling terrain it may not be easy for your opponent to find something to range on to get the desired effect with something like 3P 40mm, even with the linear depth burst option selected (which like the other modes is brilliantly modelled in SB). Of course the introduction of active protection systems in game will make it harder for them to inflict casualties on enemy armour. I expect this to expose weaknesses in Western doctrine such as over-reliance on ATGW. Snake are you modelling IR jammers and automatically triggered obscurant systems too?
