I take it in order to calculate the armour values for these monsters all I need to do is find the averages for the front sides and back (Turret and chasis respectively) and then work out the angles of the armour slope. Any idea as to what they might be?
The way I do it is I calculate the different slopes and thicknesses like
Upper Glacis 100mm @ 55 degrees = 281 mm effective
Lower Glacis 65mm @ 40 degrees = 106 mm effective
281+106 = 387
387/2 = 193.5
So effective total frontal thickness is 19cm.
Of course this all presupposes that both glacis angles are of equal height. I really need to do some measurements of actual tanks and suchlike to find the proper ratios.
But I do like this system, because it allows me to represent the changes in the JS-2s frontal armor as time goes on
