1. An illumination munition comprising a shearable tail unit, a main body which comprises a payload cavity for receiving an illumination payload apparatus, a fuze, an ogive element located between said main body and the fuze, and an explosive train operably connected to said fuze, wherein the illumination payload apparatus comprises an illumination composition, a drogue parachute and a main parachute, wherein the main parachute is tethered by a tether arrangement to the illumination payload apparatus, such that after deployment of said main parachute only the illumination payload apparatus descends under the control of said main parachute. 2. A munition according to claim 1, wherein drogue parachute is tethered by a drogue tether to the tail unit, such that upon shearing of the tail unit causes deployment of the drogue parachute. 3. A munition according to claim 1, wherein the drogue parachute is tethered by a carrier tether to a main parachute carrier and extending therethrough to a parachute delay device, wherein said carrier comprises said main parachute therein. 4. A munition according to claim 3, wherein the parachute delay device comprises the payload tether for the main parachute, a releasable engagement device to releasably receive the drogue tether, an activator which is tethered by an activator tether to the drogue tether, wherein upon activation of said activator causes release of the drogue tether. 5. A munition according to claim 1, wherein an expulsion charge operably connected to the explosive train causes ignition of an illumination delay ignitor which is operably linked to the illumination composition. 6. A munition according to claim 1, wherein the main body comprises a first threaded portion manufactured from a first material, and the tail unit comprises a second threaded portion manufactured from second material, wherein the second material has a lower hardness value than the first material. 7. A munition according to claim 6, wherein the first material is selected from a steel alloy and the second material is selected from aluminium or alloy thereof. 8. A munition according to claim 1, wherein the main parachute is a closed arm cruciform parachute. 9. A munition according to claim 1, wherein the illumination composition is at least one consolidated pellet. 10. A munition according to claim 1, wherein the ogive element is a frangible ogive element. 11. A munition according to claim 1, further comprising a locking ring located between the main body and the ogive element, to retain said illumination payload apparatus within the payload cavity, wherein the payload cavity has substantially parallel walls, which extend from the intersection of the tail unit to the locking ring. 12. A munition according to claim 1, wherein the illumination payload apparatus is capable of being dispensed rearwardly from the main body, upon shearing a shearable thread. 13. A method of dispensing an illumination payload apparatus from a munition according to claim 1, wherein the explosive train is operatively coupled to an expulsion charge, and said illumination payload apparatus is tethered to the shearable tail unit by a shearable thread, the method comprising causing initiation of the expulsion charge, which causes ignition of illumination delay igniter and shearing of the shearable thread, such that said illumination payload apparatus is caused to be pushed rearwardly from said shell, to disperse said illumination payload apparatus. 14. An illumination munition comprising: a shearable tail unit;a main body which comprises a payload cavity for receiving an illumination payload apparatus, wherein the illumination payload apparatus comprises an illumination composition, a drogue parachute and a main parachute, wherein the main parachute is tethered by a tether arrangement to the payload apparatus, such that after deployment of said main parachute said payload apparatus descends under the control of said main parachute;a fuze operatively coupled to an expulsion charge;a frangible ogive element located between said main body and the fuze; anda locking ring located between the main body and the frangible ogive element, to retain said illumination payload apparatus within the payload cavity. 15. A munition according to claim 14, wherein drogue parachute is tethered by a drogue tether to the tail unit, such that upon shearing of the tail unit causes deployment of the drogue parachute. 16. A munition according to claim 14, wherein the drogue parachute is tethered by a carrier tether to a main parachute carrier and extending therethrough to a parachute delay device, wherein said carrier comprises said main parachute therein, wherein the parachute delay device comprises the payload tether for the main parachute, a releasable engagement device to releasably receive the drogue tether, an activator which is tethered by an activator tether to the drogue tether, wherein upon activation of said activator causes release of the drogue tether. 17. A munition according to claim 14, wherein the expulsion charge causes ignition of an illumination delay ignitor which is operably linked to the illumination composition. 18. A munition according to claim 14, wherein the main parachute is a closed arm cruciform parachute. 19. A munition according to claim 14, wherein the illumination composition is at least one consolidated pellet. 20. A munition according to claim 14, wherein the illumination payload apparatus is capable of being dispensed rearwardly from the main body, in response to the expulsion charge being stimulated.
