These are Ukrainian Defenders after returning from the Russian captivity. They have lost 40 to 50 kilograms while in captivity.

In these images, they have already gained about 10 kilograms after returning to Ukraine.

The "before" and "after" photos are striking. Photographers wrote it was their hardest photoshoot in the past six months.

Thousands of Defenders remain in Russian captivity going through hell.
