I am trying to figure out the difference between the types of tank ammo; specifically what they are and when to use one versus the other. I know there is armor piercing, armor piercing composite rigid, and high explosive, but what does any of that mean really by comparison? are certain tanks more susceptible to certain ammo? I looked in the game manual in section 5.3.2.2 "ammo types" and it says "see the vehicle manual for full details", yet there is no vehicle manual in the downloads section. does anyone know where I would find that?
