Ukraine's Military Struggles with Unique Weapons and Damaged Brigades.

Two Russian marine units, the 40th and 155th Naval Infantry Brigades, have been garrisoned in towns south of Vuhledar for around a year, but have suffered heavy losses in recent months. The Ukrainian army and marine corps have focused probing attacks on Russian positions around Vuhledar, potentially making Russian defenses there fragile. The Ukrainian military has a dozen brigades in reserve and may launch a counteroffensive in the area. The 40th and 155th Naval Infantry Brigades have reportedly been reduced to combat ineffective status due to being committed to tactically flawed frontal assaults near Vuhledar.
