The Short Magazine Lee-Enfield Mark III, or SMLE Mk. III, is a British bolt-action rifle. The Mark III was an evolution of the Magazine Lee-Enfield, as the name suggests it was shortened by about 5in or 13cm, and was introduced in 1907. Complexity of manufacture meant that a simplified variant, the SMLE Mk. III, was introduced in 1915. Firing .303 British from a 10-round internal magazine, it had double the capacity of most other nations' rifles. British infantry wielding the rifle were also known for the "mad minute", an exercise during which they could reach upwards of thirty rounds per minute.
The weapon was very widespread within the Commonwealth nations, being used by Canada, the Raj, and ANZAC as well as Britain itself; many variants were developed, including the No 4 that appears in Battlefield 1942.
— In-game description
SMLE MKIII is a weapon featured in Battlefield 1 for the Scout kit. Compared to the other sniper rifles, the SMLE has the advantage of having the largest magazine size. Its sweet spot area is in the middle of the pack, at 40-75 meters.
The SMLE appears as the main bolt action rifle used by British infantry, used without attachments. The Marksman variant can be picked up from weapon crates in Through Mud and Blood and The Runner. In Nothing is Written, if a level is started without previously playing the level before, an Infantry (for the second level) and an Optical (for the third) is used as a starter weapon. SMLE MKIII Carbine is also default weapon in The Runner.
Four variants of the SMLE MKIII are featured in the game: Infantry, Marksman, Carbine and Lawrence of Arabia.
The SMLE MKIII Infantry is the basic variant of the weapon. As with other basic variants, it regains accuracy over distance due to it lack of attachments.
The SMLE MKIII Carbine variant has a shorter overall length compared to other versions of the weapon, in addition to a cheekpiece on the stock. It is equipped with a magnified aperture sight, suitable for medium range engagements, as well as a bayonet. It has marginally increased hip-fire accuracy over its longer-range versions.
Lawrence of Arabia's SMLE is a variant of the weapon exclusive to owners of the Lawrence of Arabia pack. It functions identically to the Infantry variant of the weapon, and features an unique design based on the rifle used by T.E. Lawrence himself.
- The "Lawrence of Arabia" variant of the SMLE is based on the actual rifle given to T.E. Lawrence by the Emir Faisal I of Iraq. It was originally a gift given to the Emir by Turkey.
- The cocking piece of the gun originally did not move when firing, and a later patch added the animation in.
- During several cutscenes in The Runner, some Ottoman soldiers can be seen using this weapon (such as Turkish infantryman who critically wounds Frederick Bishop). During WWI, several Ottoman soldiers used captured SMLE rifles, due to their reliablity and accuracy.
