Firstly There is no difference in zoom between all of the sights you can see this is true in the following video.

Secondly The Holographic seems to increase the accuracy of some weapons to some degree. The M-16 is one example. This doesn’t necessarily hold true for all weapons though. See the following video for a better explanation.

The Rusher

The Rusher  equips marathon and attempts to surprise an enemy by getting into an unlikely flanking position in order to get kills. They are also very adept at reacting to captured flags and the like because of their high mobility. If you are pushing hard into enemy territory chances are you’ll come in contact with groups of enemies. If you have rushed in correctly you’ll have the element of surprise and a silencer will add to the confusion your enemy faces as they realize their friends are dropping like flies around them. I prefer using the full auto weapons like the M4, ACR, SCAR-H etc for this type of role. Sure you can use an SMG as well but I don’t think the extra mobility that it gives is worth losing out on the range / damage of the assault rifles.

If you are more into running head first into your opponent and rely on your amazing reflexes, forgo the silencer as you’ll want as much oomph to your shots as possible. Guns like the M16 and FAMAS are excellent weapons for this type of role as they are a “one trigger pull one kill” sort of weapon. Don’t miss the enemies center mass and you’ll be sure to get a quick kill. Keeping mobile and moving between kills is essential to this sort of play style as your enemy will know where you are between each shot, you need to keep them guessing.

The Sneaker

The sneaker creeps around the map from ambush point to ambush point usually hiding slightly off the main travel routes waiting for an unsuspecting enemy to walk by. A silencer is essential for this type of play-style as you can easily ambush groups of enemies from behind without alerting his comrades as to your presence.

I find Bling with a RDS / silencer works wonders for this type of build, it moves forwards slowly testing each corner, looking for good hiding spots. knowing where and when the enemies will come from is a huge benefit to this sort of build. Stopping power or hardline are both great choices as when a UAV is in the air you have almost full tactical awareness.

The Long Range Specialist

The LRS fights from a distance, and uses terrain to mask his location. A silencer is almost useless as you are engaging enemies at a distance that makes your bullets less effective already. Attaching a silencer is like trying to hit them with spit balls. Since you’re so far away your shots registering on the map still won’t reveal your true location as you are not close enough for the enemy to see you on the mini map.

I like to take a shotgun as a backup weapon for this sort of play style and use either a 3 round burst AR like the FAMAS or M16, an LMG like the m240 with grip, or a trusty sniper rifle. Depending on how you like to play each gun has its advantages and disadvantages but all are geared towards a long range style of play.

Remember what Arnold said kids and “Get to the choppah!”.

I thought I would give this a go so I stood on top where this guy did with the same setup and guess what? I got killed. A lot. I can’t aim at all though so your mileage may vary.

I would have to give the edge to the FAMAS if you don’t want to take a RDS or Holo sight as your attachment. If you do use RDS or Holo pick the one that looks better since the difference is purely aesthetic.

SPAS-12

The SPAS-12 looks really badass. When you think of action movie shotgun this is the one that comes to mind. In Modern Warfare 2 it has very high damage, great range and a lower rate of fire than the other two. This gun will 1 shot kill your opponents which is the main reason I like this thing so much.

If you get the first shot off close range you can be confident that your opponent is going to go down. I can’t aim worth shit mind you so if you’re like me the next option might be a little better for you.

AA-12

If you absolutely have to kill every motherfucker in the room and you can’t really aim then this is the gun for you. Its fully auto, which means you just hold the trigger down point it in the general direction you think a guy is in and start unloading.

A great way to use this is to start firing just as you start strafing around a corner where you know some baddies are going to be. you’re already unloading shells when they become visible. I like this I really do, but I find I tend to blow the whole load at once, which means I have to spend time reloading a lot between kills. The SPAS-12 doesn’t have this problem.

Striker

The best way to describe the striker is a blend between the other two. Not as high a rate of fire as the AA-12, not as much damage as the spas-12 but it holds a lot of shells and is still full auto. You’ll be 2 shotting with this gun without using stopping power and you’ll have enough shells to deal with a crowded situation.

Only downside is this gun takes forever to reload.
