Lee Enfield

The Lee-Enfield is capable of knocking a player unconscious in two shots, with three shots being a confirmed kill. Using iron sights, it is very easy to hit human-sized targets up to 400m. This makes the Lee-Enfield especially effective when the user has the option of firing the first shot, allowing them to potentially win a gunfight with only two rounds.

Because of its high damage and accuracy, the Lee-Enfield is one of the few civilian weapons capable of competing with military-grade rifles, especially in the open countryside. However it's long length (77cm), and it's slow bolt-action system (where the next round has to be manually chambered by the user) means this is not a weapon recommended for indoor or general CQC use.

The Lee-Enfield is best used between distances of 100m-400m, (bearing in mind the need for aiming over the target at longer range). Using the Lee-Enfield in such a manner allows you to take advantage of the reasonably long effective range (400m, the second-longest of all the weapons found in civilian loot spawns aside from the CZ550.) This also allows for the Lee-Enfield to be fired from outside a settlement at players inside, reducing the chances of the user being heard by players and/or zombies.

Trivia

 * In base ArmA 2, the Lee Enfield is a one-shot kill. To prevent this common weapon from being overpowered, the devs lowered its damage
