It is used against light armored vehicles (self-propelled guns, armored personnel carriers, armored personnel carriers) protected by anti-cumulative and anti-drone means.  The 1 kg product belongs to the Shock Wave Dynamics (SWD) ammunition family.

The warhead can be equipped with the explosive C4 (420 g) or PVV-5a (390 g), consisting of 85% hexane.
EFP-S ammunition consists of:

- screws for fastening the removable part;
 
- cover for fixing the detonator;
 
- adapter for attaching to the drone frame;
 
- view to control the track camera;

The ammunition design is attached to the FPV drone using nylon clamps.  Manufacturers stated that for effective operation it is necessary to ensure remote detonation of EFP-S ammunition and calibration of the route camera before defeat.
