The Lee-Enfield No. 4 Mk I Rifle Short is a variant of the British Lee-Enfield rifles. The first Lee-Enfield models were designed in 1895, the most famous SMLE MKIII was introduced in 1907, but the No. 4 variant was designed in 1939 to answer to the need of easily manufactured rifles of the carbine. They were adopted to the British, Canadian, Australian (and other Commonwealth countries). Armed Forces in 1941, where it saw mass-production. Many wartime No. 4 rifles were manufactured in Canada due to a shortage of supplies in Great Britain, and due to the damage caused to British manufacturing by the German Luftwaffe during the Blitz.
The No 4 is a weapon featured in Battlefield 1942. It is the standard issue rifle of the Allies Engineer kit, with the exceptions of the United States Marine Corps who are issued the M1 Garand and the British Commandos who are issued the Shotgun. It has high damage, but can only guarantee a one-shot kill against a target with over 20hp (eight pips of health in the HUD) if it is a headshot - otherwise the No 4 kills in two body shots or three leg shots. The weapon is not affected by damage drop-off at range and has high accuracy, factors which bolster capabilities at distance. Recoil is significant, but is a non-issue due to the weapon's low rate of fire. The bolt must be cocked after each shot which takes around three seconds, potentially disrupting aim. This inability to quickly land follow-up shots, combined with its body-shot damage profile, means the No 4 is a particularly poor choice for close range combat. Additionally, the No 4 has a switch delay of 0.25 seconds.
The No4Sniper is a variant of the No 4, issued to the Sniper kit of the Allies. It features a usable 6X zoom scope. It has similar properties as the No 4, but with a slightly lower rate of fire and spread penalties when moving, double the bullet velocity and a larger amount of zoom. When firing scoped in, the player must unscope to work the bolt.
The No 4 Sniper is a weapon introduced in the official WWII mod for Battlefield Vietnam as the standard sniper rifle of the USMC for the Scout kit. It can kill with a single round to the head or two to the torso. It reloads one round at a time instead of inserting a clip of five rounds like in the previous game, which means it can be reloaded without the loss of any ammunition at the cost of a long reload.
— In-game description
In the singleplayer war story Tirailleur, the Lee-Enfield No.4 Mk I is the standard rifle of the Senegalese colonial troops of the Free French Forces, used by non-player characters in gameplay. In cutscenes the Lee-Enfield is replaced by either Kar98ks or Ross MkIIIs. It is also used by US Army Recons during the The Last Tiger.
The Lee-Enfield No.4 Mk I is the starting weapon of the Recon class, and is unlocked by default. Of all the bolt-action rifles in game, the weapon has the largest magazine capacity and highest fire rate, at the cost of categorically lowest muzzle velocity of 500 m/s. These characteristics make the weapon more suited for medium range engagements than its counterparts, with the rapid cycling and generous capacity being more forgiving in the event of missed shots. Per-shot damage is low but consistent, with only a difference of 5 damage between its maximum and minimum per-shot effect.
In terms of Specializations the weapon comes with Quick Aim, Custom Stock, Lightened Stock and Variable Zeroing specializations at the start. The alternative choices consist of Quick Reload, Slings and Swivels, Machined Bolt and Bayonet.
- The player character uses the weapon with the middle finger speed-firing technique - commonly called "Mad minute" due to its association with the drill - where the user operates the bolt with their thumb and index finger and pulls the trigger with their middle finger. In gameplay, this technique is reflected in the No.4's faster rate of fire than other bolt-action rifles.
