Context: The Male Zombie (also including the Female Zombie) is the backbone of all zombies. There is nothing special about them.

History: Most likely an infected citizen.

Tips: These zombies are very weak and shooting the heads is always a fast method of killing these types of zombies. You should use a machine gun, as these zombies spawn in hordes (incase you actually fight them all at the same time).

(No picture, you should be able to recognize these fast anyways. ~miqam)
