The SMLE is a weapon usable in Spearhead's first mission "Welcome to France." The player receives it when he/she meets up with a trio of British Commandos who inform the player of scattered 101st Airborne paratroopers, who give him/her a Lee-Enfield, a Mk. 2 Sten SMG, and an Enfield Revolver. It has as much power as the Springfield, but with the highest ammo capacity of all bolt-action rifles, it is essentially the best one to use in Allied Assault.
In Breakthrough, the scoped Enfield is used by Allied forces as their main sniper rifle. It is a 1-hit kill to the head and chest, 2 to the torso, and 3 hit kill on the limbs, and the capacity of 10 rounds is huge for a bolt-action of such power, these qualities make this weapon the best Sniper in the game.
The L42A1 is a scoped variant of the Lee-Enfield featured in the Breakthrough expansion pack for Allied Assault. It has a faster reload speed than its non-scoped counterparts due to its usage of magazines instead of the typical dual stripper clip feed. One inaccuracy players should know is that the gun didn't exist in WW2, but was introduced in the early 1970s instead. The British sniper rifle of WWII was the Lee Enfield No4 Mk 1 T that was basically a scoped version of the Lee Enfield No4 Mk 1 Rifle.
In Medal of Honor: Frontline, the SMLE can be seen being used by the British paratroopers in Arnhem Knights. It is unobtainable by the player. Although the paratroopers seem to use a bolt, there is no handle present on the rifle.
The Lee-Enfield is in the game Medal of Honor: Rising Sun used only by Allied NPC's, it is seen used by real-life guerilla fighter Martin Clemmens on Guadalcanal in the mission Pistol Pete and by other native guerilla fighters against IJA (Imperial Japanese Army) forces.
The Enfield typically is shown reloading via magazine changes, in reality, the magazine was only detachable for ease of cleaning, not reloading, soldiers were issued 1 spare magazine, and 12 stripper clips, this was the standard way of reloading all box magazine fed rifles of the era, including the G41, G43 and SVT 38/40 rifles
