From June 1999 to January 2003, the brigade formed the bulk of the Greek element of KFOR.

During the battle the 34th infantry regiment under Dialetis was ordered to hold the approaches at Dumlupınar at all costs and give time to the 1st Army Corps to retreat from Afyonkarahishar.

The regiment faced off against 2 Turkish infantry divisions(4th and 11th) and routed them with heavy casualties.

It successfully held the road open and the Corps managed to retreat and avoid encirclement and possible destruction.

To this day the 34th brigade is the only unit of the modern Greek army that bears the name of its former commander.
