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 Webley 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 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 bolt action rifles in the game.
SMLE as it appears in Medal of Honor: Allied Assault.
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.
Only appears in the North African campaign as one of the starting weapons the SMLE has great accuracy, range and stopping power, and is equipped with a scope. The Enfield is a good weapon to sniper enemies from a long range. Unfortunately the Enfield only has 5 rounds in it's magazine unlike in real life where the Enfield has 10 rounds in it's magazine. This may be done to balance out the weapon.
The Enfield returns in Heroes and in campaign can be picked up in a few levels. It appears in multiplayer/skirmish mode as well as a selectable starting weapon. Usually takes 2 shot to kill an enemy, one shot if it's on low health or a heashot. It holds only 5 rounds making the Gewehr-43 a superior weapon with twice as much ammo in the magazine. The Enfield uses the M1 Garand's sounds even the *ping* sound in reload. In Heroes 2 the Enfield replaced by the Springfield which model is a modified and retextured version of the Enfield's model.
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
