Band Of Brilliance

The Vector is a good close quarters submachine gun due to its high firing rate and little recoil. Despite in real life using the same powerful .45 ACP cartridge as the UMP45, in-game the Vector has the lowest damage of all the SMGs (20-25 points). This low damage makes no difference in core modes when compared to the 30-20 damage P90 and Mini Uzi, still killing in 3 to 4 hits at close range, depending on stopping power. However its high rate of fire and low recoil makes it easy to put multiple hits on target dealing lots of combined damage. It has a magazine of 30 rounds, and upon respawning in multiplayer, without Scavenger Pro, you have a total of 90 rounds, including those in the magazine in use. Due to the weapon's incredible rate of fire, it's easy to hose down an enemy and chew through a magazine quickly. It's recommended to use Scavenger Pro along with a handgun to quick switch to when out of ammo. The Vector is more usable at long range than most SMGs, second to the UMP when firing in bursts. The damage range is quite small, so the drop-off is not too significant, meaning only one shot extra depending on range. If used with the extended magazine, it can be one of, if not, the best weapons in the game; because it can drop a group of enemies in seconds with its high fire rate (which compensates for its slightly lower power), high accuracy, quick reload, and good magazine size. Stopping Powerincreases the damage from 20-25 to 28-35, bringing it to about the same damage category as the P90 and the Mini Uzi; killing in 3 hits at close range. It takes 1.8 seconds to fire through one magazine.

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 fires an even smaller round. This was probably done for balancing purposes, because the weapon has low recoil and a high rate of fire.
• In "Just Like Old Times", Soap uses a fully black Vector instead of a tan model. This is odd as the level is set in a desert.
• On the back of the Vector the player can see the words, 'Infinity Ward, Encino CA'.
• The Vector was named #1 close quarter combat weapon on Ultimate Weapons on the Military Channel. It was then a prototype known as "Kriss Super V"
• Even though the Vector model has its stock extended when on the ground, the stock must be unfolded when picked up.
• It is odd that there is recoil when firing the Vector, considering the fact that the gun uses the Kriss Super V system which should almost make the recoil go down instead of up.
• The Vector uses the stock and magazine from its civilian version, the TDI CRB/SO. Oddly enough, the ammo count is still 30, even though the CRB/SO magazine has 50 rounds,which would be practically the extended magazine attachment.
• It is unknown how the Ultranationalists got this weapon considering that it was made in the United States. They were most likely supplied by Shepherd.
• The Vector is one of the only guns to be designed so that the shooter's shoulder and shooting hand are in-line with the barrel, adding to the operator's ablility to control the recoil.
• The Vector in game kicks up during rapid fire, while in reality the Vector would kick down because of it's bolt design.
