But you got it with that pic. Ranging scale is based off tank height as depicted above. T62 was a 1500 meter tank. That is 50% of rounds fired where expected to hit at that range. For Europe that covers, well most of it. In open spaces against anything with better ranger finder.....well not so good to be in a t62 then. But during this era this was standard on many tanks. The Britsh used a ranging MG of 12.7mm on their cheiftan. I would think that would work pretty well out to 2000 meters.
Just a tad better than ww2.
