UK intelligence: More than quarter of Russia's battalion groups initially deployed in Ukraine now likely combat ineffective.

According to the recent intelligence update by the U.K. Defense Ministry, Russia has sent over 120 battalion tactical groups when it launched a full-scale invasion of Ukraine, which is approximately 65% of its entire ground combat power. Some of Moscow's elite units, such as the VDV Airborne Forces, have suffered severely and it will probably take years for Russia to replace them.
