Ukraine's military calls for silence before counteroffensive.

The Ukrainian military has urged for operational silence ahead of an expected counteroffensive against Russian forces to retake Russian-occupied territory in the east and south. Ukrainian officials have discouraged public speculation over the operation, saying it could help the enemy. The military has cracked down on citizens sharing images or footage of air defense systems shooting down Russian missiles. Kyiv's Western allies have provided weapons, armor, and ammunition for the counteroffensive, which could prove difficult against dug-in Russian forces.
