Francisco Floro, a 30-year-old from Spain, works in security back home and, like Gerber, saw defending Ukraine as a just cause.
"I believe that all the West has a responsibility toward Ukraine," said Floro. "We have to participate in this and tell the world what's happening here."
He found his way to the Territorial Defense Forces after speaking with the Ukrainian embassy back home. Despite the drama of war, Floro said the life he eventually wants is a pretty tranquil one. "I don't aspire to more than that," he said.
