Blinded after Russia invaded, a Ukrainian commander dedicates himself to helping others losing...

Col. Oleh Avtomeenko was wounded while performing a combat mission in Donetsk region, on the first days of the Russian full-scale invasion in late February 2022, and lost his eyesight.

And now, after 20 years in Ukrainian Army, he has to say goodbye to it and learn how to move on in complete darkness. But he refused to surrender.

"When you are a military, you understand why that happened to you -- because you connected your work, your profession with a certain risk for your life and health -- it was your conscious choice of yours," said Avtomeenko, 46.
