The 10mm SMG is most effective at close-range by unleashing a hail of bullets. However, the SMG is next to useless at longer ranges unless assisted by the perk Concentrated Fire. The SMG simply has too much spread to be of much use beyond close-range combat. Another downfall of the SMG is its ammunition consumption; if ammunition is not properly managed, the SMG can eat through 10mm rounds at alarming speeds. With full automatic fire and a 30-round magazine, the SMG is a decent emergency sidearm when enemies start to get too close. The SMG however is very common making it easy to repair and is definately recommended to lower level players considering that you have enough 10mm bullets.
The 10mm SMG can fire 1186 rounds, or about 40 magazines, before breaking.
Variants
Sydney's 10mm "Ultra" SMG - Relic hunter Sydney's weapon of choice, the Ultra SMG holds an astounding 50 10mm rounds in a single magazine, and deals more damage than the standard SMG.
Sim version (Operation: Anchorageadd-on) - A sim-only version of the weapon which differs only in health, with a whopping 999,250 hit points, essentially preventing the gun from ever degrading. The weapon is not accessible outside of the simulation without the use of the Gary 23 exploit or console commands. It obtained in the sim through certain equipment packs on the equipment terminal.
10mm Alloy Steel Submachinegun (Operation: Anchorageadd-on) - Another version of the weapon was cut from the add-on. Called the 10mm Alloy Steel Submachinegun, it is otherwise identical to the standard 10mm SMG.
There are many SMGs in the National Guard Depot. (Note that they are all in very bad condition.)
Several SMGs can be found inside the L.O.B. Enterprises building. There's one in the main floor's cafeteria, one on a box in the East Wing, and several in the Archives section.
