Unofficially referred to simply as ‘Mangal’ (lit. ‘barbeque grill’), this contraption is the modern incarnation of the slat armor, which consists of metal lattice or mesh mounted on a metal frame. When attached to a tank’s armor, it creates an additional layer of defense that makes it harder for drones to reach their target.
Meduza (lit. 'jellyfish') is a variation of Mangal. It consists of metal cables wired to a metal frame installed on a tank turret, which vaguely resembles its aquatic namesake. This layer of cables creates an obstacle that drones cannot get through
Dikobraz (lit. ‘porcupine’) also uses metal cables but in a slightly different fashion. Instead of just hanging down from the frame, these cables stick out like a porcupine’s needles (hence the name), their ends deliberately frayed, creating a barrier for kamikaze drones.
