[5] Immediately after the German occupation of Greece in April–May 1941, the Greek government fled to Egypt and started to form military units in exile.

Thus, in August 1942 the "Company of Chosen Immortals" (Greek: Λόχος Επιλέκτων Αθανάτων) was formed under Cavalry Major Antonios Stefanakis in Palestine, with 200 men.

[9] Initially, the unit was organized as a machine gun company and intended to be attached to the II Greek Brigade, then under formation.

Colonel David Stirling, and with the approval of the Greek HQ, the company moved to the SAS base at Qabrit in Egypt to begin its training in its new role.

[13] On March 10, 1943, in the area of Ksar-Rillan in Tunisia, the Sacred Squadron gave its first battle against a German mechanized detachment, while covering the advance of the X British Army Corps that tried to by-pass the Mareth defence line from the South.

Along with the British SBS, the Sacred Squadron took part in the successful Raid on Symi in July 1944 in which the entire German garrison was either killed or captured.

In the Hellenic Army, some of the Sacred Squadron's traditions are carried on by the Mountain Raiding Companies (LOK), founded at the end of 1946 and beginning of 1947.
