Tips? Watch for the round's splashes and adjust accordingly.
Ahahaha, if I could see their wonky impact. The only confirmation I'm getting of hits is when someone starts plinking my tank. xD
So far I've been dealing with the NATO/Abrams style sight, I haven't really messed around with much Russian items quite yet.
Also, while those range markings may not work for tanks, but they've been assisting me in anything that's got an autocannon quite a bit.
Their appears to be different damage sections as to how much a shot might do to the units total HP ala Wargame, but no true sectionalized damage, I blasted a T-55 from the rear with an autocannon, whereas meanwhile I've seen T-80Us take several TOWs (from the front). At the moment, I don't think there's much difference between tank A and tank B unless it equips something different (weapon-wise).
