The Mondragón rifle is a Mexican semi-automatic rifle introduced in 1908, and was based on two earlier straight-pull bolt-action rifles. Manufactured by SIG of Switzerland, the weapon equipped both the Mexican and Imperial German armies. In the service of the latter, the Germans found reliability to be a concern in the muddy terrain encountered by the Infantry, and so it was instead issued to the Flying Corps, where it was used by air crews until sufficient numbers of machine guns equipped with synchronization gear was available.

Additionally, in Through Mud and Blood, Mondragón rifles can be seen in hands of several German tank hunters, mainly at the end of Over the Top level, when Black Bess gets stuck in mud. These rifles have iron sights and unique drum magazine, unavailable in multiplayer.
Among the Medic's available weapons, the Mondragón offers better accuracy and control at long range, but a lower rate of fire and lack of automatic fire mode. The Mondragón may use a 2× optic with a good field of view and sharp-etched lines. Much of its damage is retained downrange, and muzzle velocity is also high. 5-round charger clips are used for reloading.
Three variants of the Mondragón are available in multiplayer: Storm, Optical, and Sniper.
— In-game Description
The Mondragón Storm is equipped with a foregrip and has a reduced recoil pattern. The Storm has the worst spread pattern of all three variants of the weapon.
The Mondragón Optical is equipped with a foregrip, a bayonet, and a magnified lens sight. It has a smaller base spread, increase per bullet, and a higher decrease per second than the Storm variant, but more recoil.

The Mondragón Sniper variant of the Mondragón is fitted with a bipod, a bayonet and a high-power scope. The Sniper has a smaller base spread than the Optical (and therefore the Storm as well), but its increase per bullet and decrease per second are on par with the Storm, which means that the Optical will have a smaller spread in sustained fire.
- The Mondragón with drum magazine seen in the cutscene of Over the Top is based on the Flieger-Selbstladekarabiner, Modell 1915, a version of Mondragón adopted by Imperial German Flying Corps featuring 30-round drum magazines.
