The 25th Armoured Brigade "2nd Cavalry Regiment - Ephesus" (Greek: XXV Τεθωρακισμένη Ταξιαρχία «2ο ΣΙ - Έφεσσος») is an armoured brigade of the Hellenic Army.

In July 1974, following the crisis with Turkey as a result of the Turkish invasion of Cyprus, the unit moved to the area of Xanthi, where it has remained since.

[1] In January 1979, the 2nd Battle Command was reorganized as an armoured brigade, and received its present name.

[1] The unit emblem was adopted in 1979, and features the head of a horse and a tank within a green circle—the traditional colour of the Hellenic Army's Cavalry–Armour arm—on a black background.

[1] It also includes the unit motto, «ΘΝΗΣΚΕ ΥΠΕΡ ΠΑΤΡΙΔΟΣ» ("Die for the fatherland"), attributed to the Ancient Corinthian statesman Periander.
