Ivan Lemeschuk was born on January 20, 1993, in the village of Haiky-Sytnenski, Radyvyliv Raion, Rivne Oblast. The fate did not have mercy on him:  his mother died early, and the grandmother Lidiia was bringing up a six-year-old boy.

Ivan studied at the local secondary school.  He was an optimist as well as an organizer of the school celebrations, tours, and excursions. Ivan was everywhere at the same time: in the gym, on the school yard, in the classroom. Close friends with whom he was hiking and making a fire to bake potatoes were always beside Ivan. Ivan was always the first in everything.

He studied at the Kremenets School of Forestry. Ivan served in the army and stayed in the military service on the contract basis. He was a paratrooper, a sergeant and a platoon commander of the 80th Air-mobile Brigade in the city of Lviv. A detachment, where Ivan served, repeatedly took part in the Anti-Terrorist Operation in Donetsk and Luhansk Oblasts.  There were victories and losses, joy and tears of despair.

Ivan Lemeshchuk died on September 5, 2014, near the town of Shchastia, Luhansk Oblast, in the battle with the Russian terrorists, who made an ambush and shelled a convoy of paratroopers where Ivan served.

According to the Presidential Executive Order №311/2015 on June 4, 2015,  he was posthumously decorated with the Third Class Order For Bravery “for valor and high professionalism demonstrated in the defense of sovereignty and territorial integrity of Ukraine, loyalty to the military oath”.
