— In-game description
Throughout the singleplayer War Stories and Combined Arms, the FG-42 is the primary weapon of both the regular German faction Support soldiers and, as seen in My Country Calling and Basic Training, British machine gunners. It can also be found in supply crates throughout the other war stories.
The FG-42 is unlocked for the Support at class rank 16. With the highest fire rate and lowest magazine capacity of the LMGs, the FG-42 has the quickest time to kill in its class at minimum range as well as high controllability with the lowest vertical recoil within its class. However, the weapon is severely range limited, dropping from to a five shot kill after just 10m, and six at 15m. This trend continues along the FG-42's entire damage curve, with the weapon generally needing between 1-3 extra bullets to kill its target. Considering this along with the small magazine and high rate of fire means the FG-42 can only engage a small number of targets before reloading, a process which is relatively expedient but necessarily frequent. Although its integral Bipod and select-fire capability allows it to engage targets at extended range, the weapon's inherent weaknesses generally compel users to adopt a more aggressive playstyle, at least compared to the other weapons in said category.
Complementing its role as an assault-style weapon, the FG-42 is the only Support weapon thus far with the ability to mount a Bayonet, done so at rank 4 of its Specialization tree. Its two general paths are geared towards improving recoil control, with the left side decreasing aiming down sight speed, vertical recoil and improving hip fire, while the right side decreases horizontal recoil while improving stationary and moving accuracy as well as movement speed through aiming.
