The RBR-120 mm M90^[1] (nicknamed Stršljen, from Serbian: стршљен, lit. 'hornet') is a light-weight, single-use, unguided anti-tank rocket launcher. The launcher is produced by Eurokompozit of Prilep, North Macedonia and Poliester of Priboj, Serbia, while the anti-tank rocket is produced by Sloboda of Čačak, Serbia.^[2] It is intended for use against tanks and other armoured vehicles in addition to fortifications and infantry.

On impact, a piezoelectric impact fuse in the rocket triggers the shaped charge warhead, which can penetrate an equivalent of over 800 millimeters of RHA.
