Vector

The Vector is a Submachine Gun in Call of Duty: Modern Warfare 2.

History
The TDI (Transformational Defense Industries) Vector uses a revolutionary design intended to decrease recoil of powerful weapons to manageable levels. Its key feature is the operating system called the Kriss Super V, a bolt that redirects the recoil downward. This combined with the repositioned trigger produces less-felt recoil in the powerful .45 ACP round. However, it also has a significantly raised sight-line. One of the only other modern submachineguns in .45 ACP, the UMP.45, handles recoil by having a lower rate of fire, so the Vector combines high stopping power with a higher rate of fire.

In Game
The Vector is a good close quarters submachine gun due to it's high firing rateand little recoil. Despite it's lack of recoil, it loses effectiveness at medium range due to damage dropoff at range. The Vector has the lowest damage of all the SMG's however its high rate of fire and low recoil makes it easy to put multiple hits on target dealing lots of combined damage.

Trivia

 * Though it has roughly the same barrel size and exact same caliber as the UMP .45, it has much less damage. It also has less damage than the 9mm MP5, which is an even smaller round. This was probably done for balancing purposes, because the weapon has low recoil and a high rate of fire.
