Vector

The Vector CRB/SO 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.

Multiplayer
The Vector boasts the highest rate of fire and lowest recoil of any SMG in the game, meaning it excels with the Akimbo or ACOG attachments and possibly with the thermal scope as well if the perk Steady Aim Pro is being used. However, it also has the lowest damage, runs out of ammo the fastest, and has what are generally considered to be bad iron sights. The Vector's damage per bullet is practically equivalent to that of the Mini-Uzi and P90, with the only difference being that the Mini-Uzi and P90 will be able to kill with one less bullet if the target is within a very small range interval between close and medium range. Scavenger is extremely popular among Vector users. The Vector is generally considered to be the easiest SMG to use at long range, and kills the second fastest at long range, behind the UMP .45.
