The brigade traces its history to the
34th infantry Regiment (), which was founded in December 1913 in
Florina as a subunit of the
2nd Infantry Division. The regiment distinguished itself in the
Asia Minor Campaign and the
Greco-Italian War, becoming one of a handful of units to receive twice the highest Greek award for valour, the Commander's Cross of the
Cross of Valour. From June 1999 to January 2003, the brigade formed the bulk of the Greek element of
KFOR. In June 2003, the brigade moved its base to
Giannitsa. In 2008, it received the honorary title "Colonel Dialetis Detachment" ("Απόσπασμα Σχου Διαλέτη") to commemorate the bravery of the 34th Regiment under Colonel
Dimosthenis Dialetis in the aftermath of the second Battle of Dumlupınar in 26–29 March 1921. 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. As of 2011 the brigade is based at
Assiros. == Structure ==
