On Feb. 23, Razil Malikov, a tank driver in the Russian army, called his family and said he would be home soon; his unit¡¯s military drills in Crimea were just about wrapping up.

The next morning, Russia invaded Ukraine, and Malikov hasn¡¯t been heard from since. On Monday, Ukraine published a video of a captured soldier in his unit, apologizing for taking part in the invasion.

¡°He had no idea they could send him to Ukraine,¡± Malikov¡¯s brother, Rashid Allaberganov, said in a phone interview from the western Russian region of Bashkortostan. ¡°Everyone is in a state of shock.¡±
