The 31M Solothurn machinegun is used primarily by Hungary in FHSW. Like most magazine feed machineguns it is never found with a tripod mount. The rate of fire is relatively low at 450 rounds per minute.
Development of the MG 30 took place under the direction of Louis Stange at Rheinmetall's Sömmerda office. Production soon followed, entering the armed forces of Germany and Switzerland as the Solothurn S2-100 and Maschinengewehr Solothurn 1930, or MG 30, respectively. 2000-3000 were also purchased by Hungary, where it was known as the Solothurn 31.M Golyószóró and replaced the Madsen LMG. The MG 30 fired both in semi-automatic and full automatic mode depending on how far the two-stage trigger is pulled, with a rate of fire between 600 and 800 rounds per minute in full-auto. It included a folding bipod attached two thirds down the barrel. In FHSW, this machine gun can be found both in stationary positions and in class kits found throughout maps.
In FHSW the MG30 only exists as an stationary weapon, it fires the 7,92x57mm Mauser cartridge and has five more rounds in each magazine compared to the Hungarian 31M machine gun. It looks identical to that machine gun.
