"When you go to bed you see it; the comrades I lost, how I pulled them out with no limbs, how they died in my arms.
"This will stay with us for the rest of our lives."
There is a darkness etched across Dmytro's eyes - the eyes of a soldier recently returned from the front line.
After 15 months of fighting in the Donetsk region, Dmytro tightly holds his wife Tetiana's hand in a recovery centre in north-eastern Ukraine.
She travelled 600 miles (966km) to this innocuous collection of buildings in the Kharkiv region after Dmytro was granted a week off.
Last year, around 2,000 troops came here for counselling and physiotherapy. Organisers admit this is just respite, not rehabilitation. Most head back to the front.
Staff at the centre say Ukraine is trying to keep its soldiers well enough to "stand until the end".
"We'll suffer the consequences for the rest of our lives," says Dmytro as his eyes moisten.
