snipers are a chosen few...not anyone can just be a sniper. one must possess the qualities and the training to be one. it is a discipline. Even if you have a rifle with a scope, that does not make one a sniper, it makes you a regular with a rifle and a scope...honing your skills is the logical next step is a designated marksman. But it takes a lot more than just patience, a rifle with a scope and a ghillie to be a sniper.
you need an extraordinary amount of patience as your field craft depends on it. another is movement, another is mastering your weapon which will enable you to hit the target with one shot giving you one kill (unless ofcourse zombie kalaban mo). one does not need a rifle to be a sniper, it can be a souped up aeg that a sniper can use.
the ability to discipline yourself the minute the nuts hits the fan is also important...by that i mean to have titanium nerves. can you stay calm in the face of the enemy being only a few feet from you? can you stay concealed even if shots are fired at your direction...or do you run away like a little girl?
in this game, most players want to be rambo or some navy seal or some universal soldier they saw in a movie. rush rush rush! but snipers are rarely like that. Their craft is mostly based on stealth
