On 15 April 2022, during the heroic defense of Mariupol at the Azovstal plant, the life of Senior Lieutenant Andriy Sydorenko, known by the call sign “Sydor,” was tragically cut short. Ukraine lost not just an experienced officer and head of the combat and special training group of the Azov Regiment, but a man of extraordinary spirit, whose life became a reflection of an entire generation’s struggle.
Andriy was born on 16 May 1980 into a large family in Fastiv, Kyiv region. His path to the ranks of defenders was deliberate and inevitable: having endured the fire of the Revolution of Dignity, he joined Azov on 17 June 2014, dedicating the next eight years to uninterrupted service.
In the memory of his comrades, “Sydor” will forever remain the epitome of a warrior-athlete. Professionally engaged in strength sports—kettlebell lifting and arm wrestling—he honed not only his own body but also the resolve of his fellow fighters, serving as their example. As recently as October 2021, at the regional championships in Kramatorsk, he earned third place among military competitors.
His athletic discipline and iron character shone even brighter in war: from the Shyrokyne operation, where he commanded a reconnaissance platoon and became an unquestioned authority for younger soldiers, to executing perilous missions in counter-sabotage and counter-sniper operations in Pavlopil, Vodiane, Mariinka, and along the Svitlodarsk arc.
Mariupol was more than a posting for Andriy—it became home. There, he found love and, in 2020, built a family, marrying the daughter of a comrade-in-arms.
Even in the final days of his life, trapped in besieged Mariupol under a hail of aerial bombs, Andriy continued to think of others. Just days before his death, he organized a fundraiser for a thermal imager. The equipment eventually reached the regiment, engraved with a poignant dedication: “In memory of Sydor.”
He died a hero at Azovstal, leaving a void impossible to fill. His brother Yaroslav fell there a month later, and his younger brother Vitaliy survived the hell of captivity. This was a family of titans, who gave everything for Ukraine.
For his courage and professionalism, Andriy was awarded a personalized weapon and the Order for Courage, III and II degrees. He was a true son of his land, deeply honoring the Ukrainian language and culture, and gave his life for the future of an independent state.
Eternal memory and glory to a faithful son of Ukraine, a brother, husband, and comrade. Rest in peace, warrior.
