Hi, I noticed that most modern tanks have barely any slope on their armour, unlike for example the old WW2 tanks like the T-34 using solid steel armour. Why exactly is this? Why is sloping of armour gone? I realize that modern armour isn't trying to deflect a shell, but still if armour is sloped 60 degrees from vertical, it would, from a horizontal perspective, be 2x thicker. Only a few tanks have sloped armour, a few Israeli and Russian ones.
