Using cover to your advantage

One of the biggest things I see people not doing to MW3 is that they are not using cover. Using cover can essentially win you the fight as long as you have more cover than your opponent or he has no cover or he luckily kills you ;P. Now what is cover you might ask. Cover is basically what you think it is. It is something that blocks your body essentially a shield. Cover protects part of your body. Giving your opponent less to shoot at. This gives you somewhat of an advantage. All you need now is to know how to use this advantage. All you need to do is get behind cover aim at your target and shoot. It also helps to strafe around to make your opponent miss. I am thinking of making a video on this but not so sure if I have time. Well that is all. Peace.
