This is the British Submachine gun of choice. It is a powerful weapon at close range, akin to the other Submachine guns, but is much rarer to find. It is much less common than the German MP40, and both have basically the same stats.
In United Offensive, the player starts the British Sicily mission with a silenced Sten. The silenced Sten looks much different from the regular Sten, with more detail, and what looks like a much larger, "chunkier" looking magazine, as well as a partial view of the thin metal stock.
The weapon is issued to the British team in multiplayer. It is not as accurate as the German MP40, making it best reserved for close quarters, where its damage and fire rate compensate for its lower accuracy.
The Sten is, again, the Submachine gun of choice for the British. It still deals a high damage in close quarters, capable of killing in just two shots. Its accuracy is good, due to low recoil and rate of fire, but loses much of its damage at extreme ranges, reducing its effectiveness at a distance. It is not encountered until the Caen missions, and is used as a starting weapon in every mission after.
This weapon is issued to the British team. It can kill in three bullets at close range or ten at a distance. Its low rate of fire and recoil make it a versatile weapon, allowing for limited medium-range combat in addition to close-range. Compared to the Thompson, it has more ammo and slightly better accuracy.
"Submachine gun. 9mm. A quick and cheap weapon to arm British troops after Dunkirk. The Sten used a horizontally-mounted 32 round magazine chambered for 9mm, so captured German ammunition could be used."
— In-game description
The Sten (listed as Sten MKII in the Bonus Materials) in this game is almost exactly the same as the previous ones. The only differences are how it is held and the Sten also appears to be weaker in Call of Duty 3. As in the previous games, the Sten has low recoil and well-designed iron sights to help the player shoot at relatively long ranges. Ammunition is plentiful in Night Drop, since many friendlies use this weapon, but in Laison River ammunition is rare until the player reaches the flak trenches and the house. In other levels, the player might end up trading it for an MP40 due to the rarity of dropped Stens.
"The Sten Mk2 was a widely copied, easy to manufacture British submachine gun."
— In-game description
The Sten is used by both the British and Canadian forces. It is held from the handguard, in a similar fashion to Call of Duty 3. If the difficulty selected is "Survival", it is replaced by the Bren. In some of the wallpapers and in the intro cinematic, the Sten was held by its magazine, but in the actual game it is held from the barrel sleeve.
The Sten originally appeared in Call of Duty: World at War, however, it was cut along with the British campaign. Only Create-a-Class image, pickup icon, animations and uncompiled weapon file remained in the Mod Tools. In singleplayer, the weapon was to appear with suppressor and without it. The model was kept for Call of Duty: Black Ops.
Unlike the most weapons, the only performance difference between the silenced and unsilenced versions is the fire rate: the unsilenced version fires every 0.1 seconds, while the silenced one can fire every 0.109 seconds.
The Sten Mk II is one of the five SMGs that appear in game, and has a fairly low damage, but also the highest rate of fire. It is the British Army's Submachine gun of choice. In singleplayer, most players will keep the Sten instead of picking up the MP40 because it has a higher rate of fire and more damage. However, players will often trade the Sten for the STG-44 in later levels because the STG-44 is more accurate, and deals more damage. In Multiplayer, the Sten is only available for the British faction, along with the Lanchester Submachine Gun, however the Sten is used more frequently, despite its lower damage, because it retains a higher rate of fire and greater accuracy.
In Call of Duty: World at War: Final Fronts, the Sten is the Submachine gun of choice for the British campaign. It is similar to past versions of the Sten in the series, and appears as a British weapon alongside the Lee-Enfield. Its ammo and damage are the same as the MP40, and it can be obtained from fallen comrades, making both this weapon and its counterpart ideal for choice, as ammo won't be a problem.
The Sten returns in Call of Duty: Black Ops and is exclusive to the Campaign level "Project Nova", being carried by the British Commandos who assault the ship containing the Nova-6 gas. It has a 32-round magazine, a moderate rate of fire, and medium recoil. Like all of the other Call of Duty games in which the Sten appears (except Call of Duty 3), it is held by the magazine, making the aim tilt slightly leftward. It is almost identical to the Type 100 from World at War, even sharing its animations, though the Sten has more recoil and more obstructive sights that hinder accuracy while aiming.
The Sten is an available layer in the game's emblem editor, although the magazine cannot be seen, as it is mounted on the weapon's side.
It has a noticeably higher rate of fire than previous incarnations of the weapon.
The Sten has low damage, high recoil which is aggravated by its fire rate and a slow reload in comparison to other submachine guns.It is unlocked by getting one of its four variants from a regular supply drop or an advanced supply drop.
It does low damage, being a four shot kill at close range and a five shot kill at medium ranges, dropping off to a six shot kill at long ranges. This, along with the high recoil, means that this weapon and its user will suffer at long ranges. It truly shines in close range, where the quick fire rate and four shot kill make it a killing machine if used properly. It is recommended to run the Sten with attachments either helping the close range capabilities or making it viable at long range. In a class focusing on close range, one should use the Silencer, Extended Mags and Laser Sight. For long range, one should use Advanced Rifling, Foregrip and a Hybrid Sight.
As stated in the in-game info for Call of Duty 3, the real-life Sten was designed to use captured ammunition, to the point of being able to use the magazines designed for the MP-40. Throughout the series, ammunition pools for the MP-40 and Sten have always remained separate.
