He began his education in Niğde. Despite difficult conditions during his childhood, he continued attending school and supported his family by herding sheep after classes.

He was described by his colleagues as a disciplined, courageous and dedicated soldier. As a protection non-commissioned officer, he was selected as one of the most trusted personnel by Major General Zekai Aksakallı, Commander of the Special Forces.

The 15 July 2016 Coup Attempt and Martyrdom

On the night of 15 July 2016, coup plotters affiliated with FETÖ moved to seize control of the state. One of the key actors in the coup attempt, then Deputy Commander of the Special Forces, Brigadier General Semih Terzi, set out with accompanying coup soldiers to capture the Special Forces Command headquarters in Gölbaşı.


Upon learning of this, the then Commander of the Special Forces, Major General Zekai Aksakallı, called one of his most trusted soldiers, Omar Halisdemir, and gave him the following order:


“Ömer, Brigadier General Semih Terzi is a traitor to the homeland. Kill him before he enters the headquarters. There is martyrdom in this end; forgive him his rights.”


Ömer Halisdemir, as clearly confirmed by official records, accepted the order without hesitation, saying: “Yes, Commander, may my rights be forgiven. You too forgive me.”


According to security camera footage, Halisdemir drew his service pistol and advanced toward the headquarters entrance. After waiting briefly, he aimed his weapon at Semih Terzi, who was moving among the coup soldiers, and fired three shots, fatally striking him in the forehead and neutralizing him. As the coup general collapsed to the ground, the accompanying soldiers turned on Ömer Halisdemir and opened fire, killing him with seventeen bullets.
