Kyiv bids farewell to Colombian volunteer soldier Jan Sebastian "Onyx" Restrepo Mazo
His path in Ukraine was full of trials: from his first days in the International Legion to service in a heavy bomber drone crew with the 413th Raid Unmanned Systems Regiment.
His comrades remember "Onyx" as a skilled fighter with numerous awards, including the "Golden Cross" from the Commander-in-Chief of the Armed Forces of Ukraine, and as a person of great kindness and a sincere soul.
"Onyx" fought his final battle near Huliaipole. When the enemy opened fire, Jan Sebastian took the blow upon himself and saved his comrades. They survived but suffered serious injuries.
At the beginning of his service in Ukraine, "Onyx" fought in the ranks of the International Legion. He later transferred to the 413th Raid Unmanned Systems Regiment, where he served as a member of a heavy bomber drone crew. Sebastian died in the battle for Huliaipole.

A respected warrior in the military circles of his homeland.
And now, of Ukraine as well.
He was wounded in infantry combat and received the Ministry of Defense's Wounded in Action distinction. He was awarded the Golden Cross and later the Oak Leaf Cluster to the Golden Cross by the Commander-in-Chief of the Armed Forces of Ukraine.
He had a kind soul. Sometimes he would return with food for a stray puppy that looked too hungry to him.
"Onyx" loved cooking and enjoyed good food.
A warrior of Christ, a professional soldier, and a fierce opponent of the communist plague. His life encompassed the military, business, criminology, and culinary arts.
Jan Sebastian was a man of many talents—kind to his friends and relentless toward his enemies.
He served in the International Legion and later in the 413th "Raid" Regiment. Jan Sebastian was part of a bomber drone crew and was killed in action near Huliaipole.
"Onyx" was captivated by the Carpathian Mountains. He fell in love with Ukraine. His final wish was to be buried in Lviv.
Sebastian's family traveled from Colombia to pay their final respects to the hero," Rick Descartes wrote on Facebook.
In accordance with his will, "Onyx" will find eternal rest in the city that enchanted him — Lviv.
