The medical battalion "Hospitallers" works directly on the front line. The battalion commander and the author of the project is Yana Zinkevych.

Hospitallers are a volunteer paramedic organization. Founded by Yana Zinkevych at the beginning of hostilities in 2014, when Russia annexed Crimea and launched hostilities in southern Ukraine with the assistance of quasi-Russian-controlled forces. Key goals:

- Help the wounded on the battlefield
- Evacuation of the wounded to hospitals
- Assistance in the rehabilitation process
- Transfer of the deceased to the place of burial in Ukraine

Members of the organization are volunteers who provide first aid to the advanced with a risk to life. So far, hospital staff have carried out more than 3,000 evacuations.

Hospitallers do not receive support from the government and provide their assistance through collaboration with volunteers and donations.
