The Madsen Machine Gun was a light machine gun designed in Denmark and first issued in 1902, making it the world's first light machine gun produced in significant quantity. First adopted by the Danish Army the weapon would be later sold in 12 calibers to 34 different countries, including France, Germany, Italy and the Russian Empire. Although expensive to produce it was recognized for its reliability, and as such remains in the service of a few armies to this day.
— In-game description
The Madsen MG is a weapon featured in Battlefield 1 for the Support kit. The detachable box magazine, which fits into the top of the weapon, can be a slight distraction. It greatly obscures view while aiming down sight, along with the action handle. This disruption is offset by the weapon's potent rate of fire, easy handling and low hip spread, as well as reloading quicker than other small-magazine LMGs if the user still has rounds left in the magazine.
The Madsen MG is the most common LMG in campaign. Its Light Infantry variant is standard weapon of Ottoman and Austro-Hungarian support units. Its Storm variant can be picked up from weapon crates in every level excluding Storm of Steel.
Owing to the fast rate of fire, good hipfire spread, and fast reload speed, the Madsen MG is an excellent support weapon to use in close quarters. However, its occlusive iron sight (and the inability to use it with an optic) along with its high recoil makes it a poorer contender for long range combat than most other support weapons. Three variants of the Madsen MG are featured in multiplayer: Trench, Low Weight, and Storm.
The Madsen MG Low Weight recovers both spread and recoil faster than the other two variants. It also has a bipod like the other Low Weight variants.
The Madsen MG Storm variant is fitted with a foregrip, granting slightly better recoil control.
