Ukrainian infiltration missions become significantly more difficult in winter, according to a special operator cited in the report. The main challenge is the loss of natural cover, which can make movement more visible and increase the risks for soldiers trying to approach positions undetected.

The report indicates that these operations are easier during the summer months, when vegetation and other landscape features provide better concealment. In warmer seasons, troops can use that cover to reduce their exposure and improve the chances of completing infiltration tasks.

Winter changes those conditions by stripping away much of the protection soldiers rely on in the field. With less foliage and fewer natural obstacles to hide behind, infiltration missions can require more caution and become harder to carry out effectively.

The contrast highlights how seasonal weather can directly shape battlefield tactics in Ukraine. As conditions shift from summer to winter, the terrain itself becomes a more important factor in planning and executing frontline operations.
