To win in battle, you must understand your opponents. Their strengths, their weaknesses, and their statistics are all vital to your strategy. Most importantly, you must know how to react when your opponent is coming at you with an army, and counter units are the key to that. Learn how to counter hordes marching upon you with lesser numbers by understanding the new armor system of StarCraft II!

Stalkers get a slight bonus to armored units, but if you're dealing with armor, Protoss has the best in the game at it. The Immortal does 150% more damage to armored units than it does to light units, and often times their counterattacks will bounce off the Hardened Shields for far less damage. Void Rays, once fully charged, melt anything Armored in fractions of a second. This includes land or air!
