The FN SCAR-H, or Mk. 17 Mod 0, is a modular, modern day battle rifle made by FNH. The L-variant of this weapon was first issued to US forces in April of 2009, with a battalion of the US 75th Ranger Regiment being the first large unit deployed with the FN SCAR.It was designed at the request of SOCOM for a multi-caliber special-forces rifle capable of marksman and CQB conversions. The SCAR-H is the battle rifle version, firing the more powerful 7.62x51mm round, making it one of the first original battle rifles since the 1950s. It has competed with the XM8 and the HK416 for general adoption by the US army, though none of the rifles were selected to replace the M4. Although current U.S. special forces mainly Army Rangers, Delta Operators, and Navy SEALs are field testing the weapon in Iraq and Afghanistan.The FN SCAR-H is my weapon of choice. It's got a small clip, but I've been able to take out 3 targets with one clip. It works well short, mid, and semi long range without a scope. And that folks is why I love it—the iron-sites are really nice, because there's no visual obstruction.

In multiplayer, the low rate of fire and high damage of the SCAR make up for its small magazine capacity. The SCAR is a one shot kill at any range in Hardcore, meaning that its minimum damage per bullet is at least 30.
It will be unlocked at Level 8 on multiplayer.
The Heartbeat Sensor is an attachment used in Call of Duty: Modern Warfare 2. The attachment allows the user to track multiple targets, somewhat like UAV and very similarly to the motion tracker in Halo 3. It displays the positions of people who are fairly close to and in front of the player. The display screen can be folded out from the side of the weapon. Its first known use is in the level Cliffhanger, where Roach finds himself in near white-out conditions. The sensor uses some kind of IFF system to tell the difference between friendlies and enemies. Friendlies are blue dots and enemies are white. In multiplayer, enemies appear as red dots instead of white.I just unlocked this recently, and it works really well. I've found myself flanking people, and camping more. When you combine that with the UAVs, you can track anyone down. The range is only good for small to mid size maps.
Oh man, I can't wait to play tonight. I'm already on level 17.
