Ukraine has used a WWI-era machine gun on the front line to mow down the enemy. "It only works when there is a massive attack going on," a Ukrainian soldier told BBC News. Ukraine's troops have modified the guns with modern add-ons such as optics and suppressors, according to reporting from Task and Purpose. The fighting in Ukraine has repeatedly garnered parallels to World War I, with both sides locked in a brutal war of attrition featuring trenches, relentless artillery barrages, and heavy casualties. In this environment, even some of the weapons of that era have come in handy as Ukrainian troops face human wave attacks on the front line — tactics common to World War I.Ukraine has also apparently utilized a type of World War I-era sniper decoy, employing dummies meant to fool enemy snipers.
