An 11-year-old boy put himself forward to defend Ukraine against the Russian invaders.
Maxim, who is in the equivalent of year 6, walked himself to a local territorial military base in Boryspil, Kyiv Oblast at night.
The young man told soldiers there that he was ready to fight and wanted to take up arms.
While Ukraine is on a war footing and throwing everything it has into efforts to repel the Russians, Maxim's offer was turned down due to his age.
Soldiers at the base, impressed by his spirit, asked Maxim if they could pose for some photos with him.
Volunteer Oleksiy Kovtun shared the story of the brave student.
He said: "An 11-year-old boy came to us at night.
"Fifth-grade student. School no. 7... He came at curfew. By himself. On foot. To the military...He came to fight!
"Then we passed him to a worried mother, who was quickly found."
Oleksiy urged the boy's mother not to "scold the hero", referring to the young boy.
The Territorial Defence Forces, which are the military reserve component of the Armed Forces of Ukraine, have been key in helping to stall Russia's ongoing invasion of its neighbour.
Though the Russian Armed Forces have occupied swathes of territory in northern, eastern and southern Ukraine, they have so far been unable to take the country's major cities, such as Kyiv or Kharkiv.
It has been suggested that Russian President Vladimir Putin underestimated the resolve and determination of the Ukrainian people and believed his so-called "special military operation" would yield a rapid victory.
Such a victory, it is believed, would have allowed him to install a puppet government in place of that of Ukrainian President Volodymyr Zelenskyy, who remains in Kyiv.
Boryspil is home to Ukraine's largest airport, which has been hit by Russian missiles during the ongoing invasion.
The city, however, still remains under Ukrainian control.
Ukraine's Territorial Defence Forces reportedly have 37,000 active members and 130,000 volunteers.
During the course of the conflict, they have been bolstered by the efforts of civilian volunteers who have produced Molotov cocktails and anti-tank traps for them.
