Multiple reports cite a senior Ukrainian defense official saying Ukrainian units are spending more time just moving to frontline positions exposed to heavy fire, effectively losing days in transit to what they describe as “kill zones.” The accounts indicate that the most dangerous period is during the movement and approach phases rather than only after troops arrive and begin fighting. As conditions on the ground deteriorate, the official warns that Ukrainian forces may eventually struggle to penetrate into these kill-zone areas because the risks and constraints have become more severe. The reporting frames the situation as a sign of increasingly intense battlefield conditions that slow deployments and raise casualties during approach, when soldiers are most exposed. The sources do not provide additional quantified casualty figures or specific operational details in the excerpts provided, but they converge on the core point: delays in reaching exposed positions are increasing, and the approach phase is where troops face the greatest danger.
