;Insurgency The unit began in February 2017 as a small reconnaissance group within the
92nd Assault Brigade. It was led by Kyrylo Veres. With only about a dozen soldiers, the unit operated in high-risk areas near
Marinka and
Krasnohorivka, conducting ambushes, raids, and missions behind enemy lines. These drones were used to drop
TM-62 anti-tank mines from the air. It resisted repeated attacks by the
Wagner Group and prevented major Russian advances over two and a half years. In the summer of 2023, during the
Battle of Soledar, K-2’s FPV drone pilots killed dozens of Russian soldiers, allowing other Ukrainian units to launch a successful counterattack with few casualties. By fall 2023, the battalion had grown to about 1,000 personnel. Along with four other elite units, K-2 became a central part of this initiative. In September 2025, the regiment was expanded to a brigade. ;Ground Drones During 2025, the unit appeared to switch from Uncrewed Aerial Vehicles (UAV) to Uncrewed Ground Vehicles (UGV), or: ground-drones. It appears to be one of - if not the - leading Ukrainian units in the development of Unmanned Ground Systems. == Structure ==
