2023 The unit was established on December 29, 2023, as the 412th Separate Battalion of Unmanned Systems, with support from the
101st Guards Brigade of the General Staff. It was tasked with destroying air defenses, disrupting logistical routes, and targeting artillery, engineering fortifications, other equipment, and personnel. After the establishment of the
Unmanned Systems Forces in 2024, the battalion became part of it.
2024 In October 2024, the 412th Separate Battalion Unmanned Systems NEMESIS destroyed a
pontoon crossing in the Luhansk region. In November 2024, a battalion operator dropped a munition on a
Buk-M2 air defense system but initially missed, causing the system to attempt an escape. On the fourth attempt, a cumulative munition struck the turret, but the extent of the damage was unclear, and it did not result in the immediate destruction of the vehicle. On November 2, 2024, a
Osa surface-to-air missile system was struck on the Luhansk front. On November 17, 2024, a
Tor air defense system, valued at approximately $25 million, was hit on the Donetsk front. On November 28, 2024, the FPV drone unit ASGARD, including airplane-type strike drones, became part of the
Unmanned Systems Forces and integrated into the 412th Battalion NEMESIS. On December 5, 2024, battalion units destroyed a 9A331M2 combat vehicle of the Russian
Tor-M2 air defense system in the Zaporizhzhia region.
2025 At the beginning of February 2025, the NEMESIS regiment destroyed an enemy
Buk anti-aircraft missile system in the Zaporizhia direction, a Russian
BM-21 "Grad" MLRS in Luhansk Oblast. In late February 2025, the regiment claimed that it destroyed a
M-1978 Koksan in
Luhansk oblast. Footage of the claimed attack was published on Telegram. Over a month, from December 2025 and January 2026, the 412th Brigade destroyed some $250 million worth of air defence systems including a
S-350 Vityaz and “two
Tor-M2 systems, two
Buk-M1 systems, one
Tor-M1 one
Buk-M3, and one
Strela-10 short-range air defense system”.{{cite news |author= Sofiia Syngaivska |title= Over $250 Million in russian Air Defenses Destroyed by Ukraine's Asgard Battalion (Video) == Structure ==
