In April 2001, the Ukrainian component of the International Engineer Battalion "Tysa" was subordinated to the 534th engineer and sapper battalion, stationed in the city of Vynohradyv. In the winter of 2015, units of the battalion took part in battles near Debaltseve. Under the command of Captain Serhiy Melymuka, mine barriers were installed at the "Lyokha" airfield near Sanzharivka. In the battle on January 21, 2015, thanks to them, losses were inflicted on the occupying troops who tried to break through the stronghold.
