1: ALWAYS use rapid-fire.
2: The Holographic sight and ACOG sights work fine.
Mil-dot, Omega and Triangle are the best sights because they don't clutter your sights and allow you to see UNDER your dot which is important when compensating for the recoil.
3: Use quickdraw and a sensitivity of at least 4-5.
4: Aim for the groin, and just let the recoil do the rest.
This will have you hit them even when you get hit.
5: Remember to adjust your rate of fire for the distance:
Close: Spam
Short: Spam
Medium versus target in the open: Fast
Medium versus target in a window: Pop three shots on target
Medium versus a head over a wall: Pop one single accurate shot for a one hit kill
Long range: Pop untill the enemy stops
Versus a target in a window: Fire single shots and let the recoil visually settle and make sure the next shot is on target -- it takes under 1 second to fire 3 hits.
Long range vs a head: RUN! It's a sniper! Or else: Two hits will remove the head.
6: A suppressed Mk14 has a lower rate of fire than a stock Mk14.
One way to deal with this, unless you hit the fire cap all the time, is to run Kick on all your Mk14 profiles without a suppressor, and run rapid-fire silencer on the profiles with a silencer. That evens out their rates of fire to the point where switching is painless.
7: Stingers > Assassin, for the Mk14. Stalker can also free up perk 2, which HAS TO go to Quickdraw.
8: Review your games when you lose in theater mode.
Were you behind cover?
Were you taking the longest route around the objective with the unsuppressed weapon or were you taking the dangerous shortcut?
Did you run while in a dangerous area, or did you crouchwalk?
What happened to your claymore or bouncing betty?
Why did you get shot in the back?
Where does the enemies actually spawn?
Where should you pre-aim because the area ahead has a high probability of having an enemy?
9: This is a connection-based game.
Learn to spam the trigger, pre-aim and pre-fire for the best experience.
When the game lags, treat your trigger as your worst enemy and SPAM it properly.
You will find that somehow, spamming the trigger makes enemies die more often -- especially during times of lag.
Don't bother spamming when you have a good connection, unless the opposition is good.
Spamming decreases your deaths.
10: The Mk14 kills in one hit to the head or neck up to 27.5 meters.
It kills in two hits up to 48.5 meters, and three hits therafter -- being the assault rifle with the best range and best damage on long range.
Keep in mind that the ACR and G36C needs 4 hits to kill at 34 meters range while you only need two hits; Take your time on longer ranges, do not spam anywhere else than medium and short range, and when hip-firing.

Fast equipment guide:
Claymore: Place it facing a barrel or the front of a car in the direction the enemy is coming from.
Bouncing betty: Crouch and throw it just under a car an enemy may pass, or next to a barrel.
Semtex: When you're on the offense and don't need a carbomb.
Flashbangs: Throw far up ahead into the air over buildings and over the streets on the other side to probe the area with recon pro.
Portable radar: Throw it in a high traffic area or near an enemy objective to help your team, and DO NOT camp it.
I tend to throw it on top of buildings, because it makes it practically indestructible and makes it hard for the sitreppers to see it and avoid it.
When used against enemies, wait till they empty their guns before you kill them.
I use stingers on ALL my classes.
Enemy UAV or Care Package or Attack Helicopter or Reaper = One more point to my pointstreak.
Straferun = Jackpot
Recon Drone: This helicopter has two sets of countermeasures, so don't even bother.
Assault Drone: Yes. The stinger works on them, and yes -- the stinger is super-effective vs personell when you hit the Assault Drone, and one hit kills it.
