The present invention describes a projectile (100,100a,100b,100c,100d) containing two luminescent dye components (123,125) and a dye powder (126). The first luminescent dye component (123) is contained in an ampoule (122) while the second luminescent dye component is contained in a vial (124) disposed inside the ampoule (122). A front crusher (120,120a) is provided at a front of the ampoule to crush into the ampoule and vial, thereby allowing the dye components to react and give a luminous glow. Upon impact at a target, a nose cap (110) of the projectile (100,100a,100b,100c,100d) breaks and a rear crusher (130) behind the ampoule throws the ampoule (122) forward and sputters the luminous dye out of the nose cap (110); at the same time, the dye powder (126) surrounding the ampoule is sputtered out to mark the point of impact. In addition, a thermal glow is also provided to mark the point of impact. Projectiles also allow light tracing.

1. A projectile having a hollow nose cap threadedly connected to a forward portion of a projectile body and a cartridge case bonded to a rear portion of said projectile body, such that said projectile is elongate and defines a longitudinal axis; wherein said projectile comprises: an ampoule disposed inside said hollow nose cap, with said ampoule's longitudinal axis substantially coaxial with said longitudinal axis of said projectile, and said ampoule contains a first luminescent dye component;a vial disposed inside said ampoule, with said vial containing a second luminescent dye component;a front crusher disposed at a front end of said ampoule; anda rear crusher disposed at a rear end of said ampoule;wherein upon launching of said projectile, impulse of said front crusher crushes said front end of said ampoule and said vial, thereby allowing said first and second luminescent dye components to mix and produce a luminous glow, and upon said projectile striking a target, said nose cap breaks and then said rear crusher throws said luminous dye out of said broken nose cap to mark the point of impact of said projectile. 2. A projectile according to claim 1, further comprising a dye powder disposed around said ampoule and front crusher. 3. A projectile according to claim 2, further comprising a filler plug to keep said dye powder in place after said inside hollow of said nose cap is filled. 4. A projectile according to claim 3, wherein said dye powder is contained in a sachet. 5. A projectile according to claim 3, wherein said filler plug has a hole at its centre for receiving said ampoule. 6. A projectile according to claim 2, wherein said dye powder comprises a catalyst that is reactable with said luminescent dye to produce a glow that is stronger than said-luminous glow of only, said luminescent dye. 7. A projectile according to claim 1, wherein said front crusher, ampoule and rear crusher are substantially coaxial along said longitudinal axis of said projectile. 8. A projectile according to claim 7, wherein external dimensions of said ampoule and rear crusher are substantially the same. 9. A projectile according to claim 1, wherein said front crusher is relatively smaller than an interior dimension of said ampoule. 10. A projectile according to claim 9, wherein a rear face of said front crusher has a cutting edge that is in contact with said front end of said ampoule. 11. A projectile according to claim 1, wherein said ampoule is made of a plastic material whilst said vial is made of glass, or vice versa. 12. A projectile according to claim 1, wherein said rear crusher is disposed in a recess that opens from said forward portion of said projectile body. 13. A projectile according to claim 12, wherein an interior surface(s) of said recess and/or said filler plug is/are deposited with a phosphorus compound and an exterior surface(s) of said rear crusher and/or ampoule is/are deposited with an oxidant that is reactable with said phosphorus compound. 14. A projectile according to claim 12, wherein an interior surface(s) of said recess and/or said filler plug is/are deposited with an oxidant and an exterior surface(s) of said rear crusher and/or ampoule is/are deposited with a phosphorus compound that is reactable with said oxidant. 15. A projectile according to claim 12, wherein said rear portion of said projectile body comprises a channel that communicates said recess to said rear of said projectile body. 16. A projectile according to claim 1, wherein said rear portion of said projectile body comprises a centre hole that is plugged with a transparent polycarbonate plug. 17. A method of marking a strike point of a projectile noticeable, said method comprising: breaking an ampoule and a vial contained in said ampoule by a front crusher during launching of said projectile, mixing two luminescent dye components separately contained in said ampoule and vial to give a luminous glow;breaking open a nose cap of said projectile along a line of thickness transition upon impact at a strike point; andsputtering said luminous dye out of said broken nose cap by a rear crusher to mark the strike point;wherein said method is used during the night and with the aid of a night vision camera. 18. A method according to claim 17, further comprising: catalysing said luminescent dye with a dye powder to give said luminescent dye a stronger glow. 19. A method according to claim 17, further comprising channeling heat from propulsion gas from a rear of said projectile body to said ampoule and vial to thaw said luminescent dye components when said projectile is used in a cold environment. 20. A method of marking a strike point of a projectile noticeable, said method comprising: breaking an ampoule and a vial contained in said ampoule by a front crusher during launching of said projectile, mixing two luminescent dye components separately contained in said ampoule and vial to give a luminous glow;breaking open a nose cap of said projectile along a line of thickness transition upon impact at a strike point;sputtering said luminous dye out of said broken nose cap by a rear crusher to mark the strike point; andsputtering a dye powder out of said broken nose cap; wherein said method is used during both day and night. 21. A method according to claim 20, further comprising: catalysing the luminescent dye with said dye powder to give the luminescent dye a stronger glow. 22. A method according to claim 20, further depositing a phosphorus compound and associated oxidant separately on two cooperating surfaces, and allowing said oxidant and phosphorus compound to rub and ignite and thus providing a thermal glow as said rear crusher is thrown out of said projectile body at the point of impact; wherein said method is used with the aid of a thermal imaging camera. 23. A method according to claim 20, further comprising tracing said luminous glow that is emitted through a transparent plug disposed at a rear of said projectile body. 24. A method according to claim 20, further comprising channeling heat from propulsion gas from a rear of said projectile body to said ampoule and vial to thaw said luminescent dye components when said projectile is used in a cold environment.
