  2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass
    - das Unterscheidungsorgan (50, 66) eine getroffene Zielvorrichtung (60) je nach Verwundbarkeitskriterium als zerstört bestimmt (203).
  3. Verfahren nach einem der Ansprüche 1 bis 2 dadurch gekennzeichnet, dass
    - man das Erfassungssignal dazu nutzt, um in der Zielvorrichtung (60) einen Alarm (65) auszulösen.
  4. Verfahren nach einem der Ansprüche 1 bis 3 dadurch gekennzeichnet, dass, wenn das Unterscheidungsorgan (50, 66) von der Zielvorrichtung (60) getragen wird,
    - eine Zielvorrichtung (60), die den Strahl erfasst hat, eine Signalisierung (81, 104) für die Laserschusserfassung in Richtung anderer Zielvorrichtungen (60) erstellt,
    - dieses Organ die erstellte Signalisierung mit Signalisierungen vergleicht (107), die sie von anderen Zielvorrichtungen (60) empfangen (106) hat, und
    - je nach empfangenen Signalisierungen der Charakter für getroffen oder nicht getroffen jener Zielvorrichtung (60) bestimmt wird, die die Signalisierung erstellt hat.
  5. Verfahren nach Anspruch 4, dadurch gekennzeichnet, dass
    - man ein Fenster (105) zum Abhören der empfangenen Signalisierungen als Antwort auf die erstellte und ausgesandte Signalisierung öffnet,
    - die empfangenen Signalisierungen vorzugsweise dieselben Merkmale enthalten, wie die erstellte Signalisierung, und
    - man die Unterscheidung am Ende dieses Fensters abschließt, wobei es durch diesen Abschluss möglich ist, zumindest eine Zielvorrichtung (60) unter jenen Zielvorrichtungen (60) zu bevorzugen, die einen jeweiligen Laserschuss erfasst haben.
  6. Verfahren nach Anspruch 5, dadurch gekennzeichnet, dass
    - die Abhörphase die folgenden Schritte umfasst:
    - man vergleicht für jede empfangene Signalisierung die Merkmale jeder empfangenen Signalisierung mit den Merkmalen der erstellten Signalisierung,
    - wenn die empfangenen Merkmale von den erstellten Merkmalen abweichen, nimmt man sie aus der Unterscheidung heraus,
    - ansonsten speichert (108, 109) man die empfangene Signalisierung ab, und
    - man führt die Unterscheidung nach Ende des Abhörfensters auf Basis der gespeicherten Signalsierungen und der erstellten Signalisierung durch.
  7. Verfahren nach einem der Ansprüche 1 bis 6, dadurch gekennzeichnet, dass
    - man die Signalisierungen über eine Übertragungsvorrichtung (61) der Zielvorrichtung (60) einem Kommunikationsnetzwerk übermittelt.
  8. Verfahren nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, dass bei Abgabe des Schusses :
    - mit der Simulationswaffe (14) auf die zu erreichende Zielvorrichtung (60) gezielt wird,
    - man mit dem Laserstrahl zeitabhängig eine Abtastung am Ort des Laserschusses simuliert, um ein ballistisches Verhalten einer Munition darzustellen, deren Flugbahn (T) von der Simulationswaffe (14) simuliert werden soll,
    - man den Abstand (D) zwischen der Simulationswaffe (14) und der Zielvorrichtung (60) misst, und man so einen gemessenen Abstand erhält,
    - man in der Zeit ein Einschlagdatum (ti) eines Laserstrahls auf der Zielvorrichtung (60) in Bezug auf das Schussdatum (t0) ortet,
    - und man überprüft, ob sich das Einschlagdatum in der Zeit innerhalb eines Zeitfensters (A0) befindet, das an einem entsprechenden Datum über eine Relation zum gemessenen Abstand festgehalten wird.
  9. Verfahren nach Anspruch 8, dadurch gekennzeichnet, dass bei Abgabe des Schusses
    - man ein Verhalten einer seitlichen Bewegung der Zielvorrichtung (60) misst,
    - man die Simulationswaffe (14) je nach Zeit in Abhängigkeit des Messwerts dieses Verhaltens versetzt ansetzt (31).
  10. Verfahren nach einem der Ansprüche 8 bis 9, dadurch gekennzeichnet, dass
    - die Signalisierung Merkmale des erfassten Laserschusses, der Art des Ziels und der Werte der Unterscheidungskriterien umfasst.
    - ein Unterscheidungskriterium vor allem die erfasste Leistung des Laserschusses, eine Abweichung zwischen einem Einschlagpunkt des Laserschusses und einem kritischen Verwundbarkeitspunkt oder eine Abweichung zwischen dem gemessenen Abstand und einem Ist-Abstand entsprechend dem Einschlagdatum ist.
  11. Verfahren nach einem der Ansprüche 1 bis 10, dadurch gekennzeichnet, dass
    - man einen Prozentsatz des verbrauchten Lebens des getroffenen Zieles über eine Matrix des Zerstörungsprozentsatzes errechnet, die zuvor festgelegt worden ist.
  12. Verfahren nach Anspruch 11, dadurch gekennzeichnet, dass :
    - man das Erfassungssignal auslöst, wenn der Prozentsatz des verbrauchten Lebens größer oder gleich 100% ist.
  13. Verfahren nach irgendeinem der Ansprüche 1 bis 12, dadurch gekennzeichnet, dass die Kommunikation zwischen den Zielvorrichtungen (60) durch ihre Übertragungsvorrichtungen über ein Netzwerk entsprechend einer öffentlichen oder einer eigentümerspezifischen Norm und/ oder durch die Erstellung eines bidirektionellen dynamischen Netzwerks und/ oder im Ausstrahlungsmodus erfolgt.
  14. Zielvorrichtung (60) umfassend :
    - einen Lasersensor (63),
    - einen Alarm (65),
    - einen Rechner (66), der mit dem besagten Sensor (63) und mit dem besagten Alarm (65) gekoppelt ist, dadurch gekennzeichnet, dass
    - die Vorrichtung (60) einen Laserreflektor (64) umfasst, der mit dem besagten Rechner (66) gekoppelt ist,
    - der besagte Rechner (66) einen Unterscheidungsprogrammspeicher (71) umfasst, der so konfiguriert ist, dass er ein Merkmal für getroffen der besagten Zielvorrichtung (60) in Abhängigkeit von den Signalisierungen der Zielvorrichtungen (60) bestimmt, die nach dem Verfahren irgendeines der Ansprüche 2 bis 13 einen Laserstrahl erfasst haben.
  15. Mechanischer Kampfteilnehmer (10, 15) zur Trainingssimulierung, auf dem eine Zielvorrichtung (60) nach Anspruch 14 installiert ist.
  16. Zentralcomputer (50) zur Abwicklung einer Simulierung eines Kampftrainings, umfassend :
    - Vorrichtungen zum Empfangen der Erfassungssignalisierungen von Schüssen, die von Zielvorrichtungen (60) ausgesandt wurden,
    - Unterscheidungsvorrichtungen, die so konfiguriert sind, dass sie ein Merkmal für getroffen einer der Zielvorrichtungen (60) bestimmen, indem sie nach dem Verfahren irgendeines der Ansprüche 1 bis 13 zumindest ein zuvor bestimmtes Unterscheidungsmerkmal auf die empfangenen Signalisierungen anwenden.
