Army of Two Hints
Really Frickin Easy Way To Kill Armored Enemies
Just purchase a shotgun. The shotgun will knock him down with one shot. You can either finish him there or when he starts to get up, you can shoot him in the unarmored section of his back. Piece of cake!

Killing Armoured Gunners Without Stealth
If you encounter an armored opponent, the Aggro Training tells you that one person holds the position, while the other tries their best not to get seen by the opponent to shoot them from behind. Now, the easy and fast way to do it is to shoot him with any gun, in the head. Soon, he will either die, or fall to the floor, not injured, but defenseless. That is when you shoot at him wherever. WARNING!!! This process is to be done as quickly as possible, or he will get up and shoot at you if you are close enough. So basically, your strongest weapon against the armored opponents, can be the worst weapons.
