I noticed lots of people don't really understand how the armor system in this game works, so i'll try to make it a bit clearer.
Armor is devided in 3 sections:
The armor value is displayed like this:
"thickness of the armor" (millimeters mm) @ "angle of the armor" (degrees °)Most armor is sloped (at an angle). The lower the angle, the higher the protection with the same armor thickness. For example: 30 mm armor at 35 degrees will be a lot more protective then 30mm armor at 90 degrees. After all, if the shell from a direct straight shot (and this is very important, it has to be a straight horizontal shot) hits the armor at 35°, it will have to penetrate much more armor then when the armor is angled at 90°
I'll give an even better example: 53mm armor at 30° has the same protection value as 100mm armor at 90°. I call this "relative armor thickness"
I'll explain "relative armor thickness" with an image:
You can clearly notice the black arrow is much longer than the green arrow. I've made a comparisation-table that displays the relative armor thickness of each tank for the front, side and rear armor. WARNING: This table is only accurate to compare armor protection against a direct straight shot (from tanks, tank destroyers and assault guns). Self propelled guns (artillery) use indirect fire and have a different effect on armor. Because the shells land at an angle as well, it's impossible for me to calculate the protection against indirect fire. I've currently only calculated the relative armor for the tanks from level 1 to 7 for both nations. I might do the other tanks as well, but this will be for later. This list should already help you compare the light tanks of both nations If you used armor upgrades and want to calculate your relative armor thickness, you can do this with this tool (Thanks to Jetu)
I hope this helps understand the way armor works in this game. If anyone has any questions, i'll try my best to help you. Also, any suggestions to improve this guide will be appreciated. CREDITS |
