The index at the bottom of each picture describes a few abbreviations used and also the format in which the armor details are described in. Effective Armor (EA) refers to the overall effectiveness of the armor without normalization. The armor values are presented in three different scenarios for the angled view of the tank. 15° frontal(75° side), 25° frontal(65° side), 35° frontal(55° side), and 45° frontal(45° side). So as you angle the front of the Type 59 the sides become progressively weaker since the angles on the side hull are reduced.
World of Tanks Type 59 Weak Spots Frontal View
Frontally the Type 59 is a formidable foe for most tier 8 tanks and below due to it’s awesome turret armor and also it’s above average hull armor for a medium tank. The turret front on the Type 59 is immune to almost everything thrown at it aside from a few locations located around the center towards the bottom where it drops to a minimal 204mm effective armor. Otherwise the turret hatches do have several weak spots on them that are able to be exploited if you have an accurate shot on them. The frontal hull armor is covered by 100mm armor and is difficult for a lot of tanks the Type 59 faces to penetrate reliably. The lower frontal glacis sitting at 170mm effective armor is a great weak spot to use as long as you are 100m or further away from the Type 59. As you drop below 100m the upper hull starts to lose its effective armor and the lower glacis becomes tougher due to the angle you are firing at.
World of Tanks Type 59 Weak Spots Angled View
A lot of Type 59 drivers angle their tank which increases the frontal hull armor immensely. However it opens up their weak side armor to easy shots as you can simply hit the USH/LSH or shoot the frontal track wheel for easy damage.
