Today I am going to discuss aiming, why? Because a lot of guys are firing way too many shots or not enough. Most or all of what I am going to type up here is most likely in Basic Marksmanship Training which you should retake if you notice a decrease in your accuracy.
1. Aiming your rifle
While aiming you're rifle, in this guide the M-16, you'll want to be prone or crouching, do not stand up or lean unless absolutely necessary. Also ALWAYS use your sights, even in CQB. It may not be as effective in CQB but if you are taking hits your shot pattern won't be as random.
2. Types of aiming
There are 2 types of aiming that I will go into depth later, 1 is Long Distance Shooting AKA Sniping. While sniping you'll want to be crouching, prone if possible, and in the semi-automatic fire mode. The other type is Speed Shooting, which is most commonly used. In speed shooting you don't fire until you see someone. Once you see someone, raise sights aim and shoot off a couple of rounds.
3. Long Distance Shooting AKA Sniping
While sniping you'll want to take your time, NO UNECESSARY SHOTS. Aim at your target while crouching, preferable prone, wait until they present to you the best shot you can possibly get, aim for the chest, wait for your character to hold his breath, then fire. You want to be doing this in the semi-automatic fire mode. The text book take down is 1 shot, 1 kill without anyone spotting you. Once the target is eliminated search the surrounding area for his teamates, if clear leave your position and either move up or find another.
4. Speed Shooting
The best practice for this is in basic training. Only raise your sights up when you see a target, fire 2 shots per target. This is mostly used when advancing and you suddenly see someone, you raise your sights and quickly shoot at them. There are 2 things that can be done while speed shooting. 1, Kill them or 2, you can suppress them in hopes of flushing him out or letting a teamate flank him. Speed shooting doesn't really require a big explanation, just look, aim, and shoot.
