The Russian military advance west and north is accelerating. From Moon of Alabama at moonofalabama.com:
In 2023 the situation in Ukraine had developed into what looked like a stalemate. But 2024 proved that bigger things had been in the making. In 2024, after taking Avdivka, the Russian forces began to deliberate and steadily move forward.
The introduction of FAB bombs, precision ammunition delivered from airplanes flying outside Ukrainian air defenses, broke the Ukrainian defense fortifications. Russian infantry, covered by ample artillery and with the help drones, infiltrated and overwhelmed Ukrainian lines. An ever increasing shortage of Ukrainian troops helped to increase the tempo of progress.
Diversion action, by Russia in the Kharkiv region and by Ukraine itself due to its attack into the Kursk region, further weakened the Ukrainian lines. A high number of casualties, unmotivated troops and a lack of heavy equipment have since diminished the Ukrainian forces. The downward spiral the Ukrainian army is currently in is likely to continue.
During the last six month the main frontline in south-east Ukraine has changed significantly.
