50th Mechanized Infantry Brigade (Greece)
The 50th Mechanized Infantry Brigade "Apsos" () is a mechanized infantry brigade of the Hellenic Army. It is headquartered in Soufli as part of IV Army Corps.

History 
The brigade traces its history to the 50th Infantry Regiment (), which was founded in 1919 in Adrianople (now Edirne in Turkey).

The regiment fought in the Greco-Italian War in the Albanian front until the capitulation of the Greek Army following the German invasion of Greece in April 1941. After liberation, the regiment was reformed, initially for a short period as the 32nd Brigade (32η Ταξιαρχία), and stationed at Eleftheroupoli. Between 1964 and 1988 it moved its base from Eleftheroupoli to Feres, Pythio, again to Eleftheroupoli and then briefly to Koufovouno. In summer 1988 it was transferred to Soufli, where its expansion to brigade began.

The 50th Infantry Brigade (50ή Ταξιαρχία Πεζικού) became operational on 1 October 1988, although its formation was not completed until two years later. In September 2000, the formation received the honorific title "Apsos" after the river Osum (Apsos in Greek) in southern Albania, where the 50th Infantry Regiment distinguished itself in battle on 25 January 1941. The brigade was converted to mechanized infantry in 2003, acquiring its present title.

Emblem 
The brigade's emblem features a purple triangular shield upon which is depicted a golden sphinx wielding a poleaxe. A scroll underneath the sphinx bears the unit's abbreviated title. The whole is edged in white, with an inscription above with the unit's motto, Αρχή του νικάν το θαρρείν ("Courage is the foundation of victory"), a quote from Plutarch (Life of Themistocles, 8.2) referring to the Battle of Artemisium in 480 BC.
