Ukraine grapples with a shortage of troops at the front after over 4 years of war

KYIV, Ukraine -- Ukraine’s advances in drone technology and tactics have captured the world’s attention. Despite those innovations, one problem has plagued the country since the start of Russia’s invasion: a shortage of combat-ready troops.

Ukraine always has been outmanned by Russia, but as the war drags through its fifth year, the need for personnel is increasingly acute, commanders and analysts say, with some units at only half strength. There just aren't enough forces to fully exploit the battlefield advantages resulting from the drone innovations.
