Yugoimport M-4 (BR-4)

The Yugoimport M-4 (also designated BR-4) is Serbia's domestically developed loitering munition representing an effort to enter the rapidly growing unmanned strike systems market building on Yugoslav-era defense industrial expertise. The M-4 uses vertical launch enabling deployment from confined positions without launch rails, an electro-optical seeker for target identification, and a warhead designed to defeat light armored vehicles, personnel, and material targets. The system was developed primarily for counter-UAV applications as a kinetic drone interceptor using a kamikaze engagement profile, as well as offensive loitering strike capability against light targets. Development was driven by Serbia observing the decisive combat role of loitering munitions in Nagorno-Karabakh and Ukraine, and the determination to acquire this capability domestically rather than face the political complications of purchasing from established exporters. The M-4 represents Serbian defense industry emerging in a new weapons category with significant export potential to non-aligned and developing nations seeking affordable precision strike capability.
