Abstract: The invention relates to programmable practice ammunition. For this purpose, a projectile head of a practice projectile of the practice ammunition has at least one electronic system in the form of an electronic fuze replacement system and a signal transmitter. Optionally, an explosive charge can be introduced into the projectile head. The explosive charge is preferably a pyrotechnic. A light signal, an infrared signal, a radio signal, or another suitable electronic or optical signal, even a color signal, can be output and transmitted via the signal transmitter. Optionally, the explosive charge can be triggered and deployed via the signal transmitter. The projectile is provided with radial openings for this purpose. The invention additionally relates to a training system for a realistic practice using an explosive representation at the target or in the target area.
