Photo and video evidences from Donbass depict that Ukraine’s military uses World War 2 era weapons.
The Kiev authirities can’t guarantee supplies of munition to the contact line and “NATO allies” don’t help the Ukrainian forces with lethal weapons. This is why the troops at the forntline are pushed to use all what they can find.
The Ukrainian Armed Forces use actively 203 mm howitzers M1931 (B-4), which was designed in 1931, and heavy machine guns PM M1910, designed in 1910. According to reports, many examples of these weapons have been supplied to Ukraine from the Baltic states.
