'Ghost Brigade'), founded by Aleksey Mozgovoy, is an infantry unit of the Luhansk People's Republic (LPR), one of the self-proclaimed breakaway states located in the Donbas.

However, the Prizrak Brigade deliberately stayed outside the developing umbrella structures among the separatists, initially neither joining the Army of the South-East or the LPR People's Militia.

Separatist authorities blamed Ukrainian assassins, but investigators and members of his unit suspected that his local rivals were responsible.

[8] Researcher Mark Galeotti argued that the assassination was "mysterious" and noted that the Prizrak Brigade ceased its great autonomy following Mozgovoy's death.

[16][17] The Prizrak Brigade considers itself both a military combat unit as well as an anti-Imperialist and revolutionary socialist political organization.

[19] In 2015, a far-left military political unit composed of internationalist volunteers called "Interunit" was built inside the Prizrak Brigade, and operated until 2017.

[2] A former Ukrainian POW of the Prizrak Brigade told Amnesty International that his captors had brutally mistreated him and other prisoners, with daily beatings, near-starvation, and stabbing and shootings.
