Armies have been storming trench lines for more than a hundred years, but for all the advances in military technology, it is no less harrowing now than it was when soldiers were crossing the muddy battlefields of World War I.
Assaults can be stealthy and surgical, employing surprise, or launched with overwhelming force, using drone strikes, or tanks and artillery.
Ukrainian soldiers chose the louder option for an assault on a trench line in May.
Then armored Humvees bounced forward over a field, firing machine guns, the men said.
The assault group fired 3,000 bullets from two American-provided Browning machine guns, one commander named Kozak said, in an indication of the immense ammunition requirements for troops on the offensive.
