1. A short-range, self-propelled, non-fragmenting breaching device comprising: a high-density, composite housing;a nose fuze assembly disposed at the forward end of the housing, wherein the nose fuze assembly includes a detonator;a cartridge case assembly disposed at the aft end of the housing, wherein the cartridge case assembly includes a propelling charge and a primer to ignite the propelling charge; andan explosive charge disposed between the nose fuze assembly and the cartridge case assembly, wherein the explosive charge has a weight that is greater than 50 gramswherein the breaching device has a minimum effective range of 10 meters,wherein the nose fuze assembly is point-initiating, andwherein the detonator detonates the explosive charge upon impact of the nose fuze assembly with a target. 2. The breaching device according to claim 1, wherein the explosive charge composition comprises an a insensitive explosive. 3. The breaching device according to claim 1, wherein the weight of the explosive charge is in a range of 50 grams to about 300 grams. 4. The breaching device according to claim 3, wherein the weight of the explosive charge is in a range of 50 grams to 150 grams. 5. . The breaching device according to claim 4, wherein the weight of the explosive charge is 150 grams. 6. The breaching device according to claim 1, wherein the breaching device is a close-quarter offensive grenade with minimum fragments to reduce collateral damage. 7. The short-range, self-propelled, non-fragmenting breaching device of claim 1, wherein the composite housing contains a plastic compounded with a high density metal powder. 8. A method of preparing the breaching device of claim 1, the method comprising the steps of: (a) filling a high-density, composite housing with an explosive charge;(b) assembling a cartridge case assembly to the aft end of the housing; and(c) assembling a nose fuze assembly to the forward end of the housing. 9. A method of breaching a target using the breaching device of claim 1, the method comprising the steps of: (a) loading the breaching device into a weapon launcher; and(b) launching the breaching device to breach a barricade target. 10. A short-range, self-propelled, non-fragmenting, door-breaching 40 mm grenade comprising: a high-density, composite housing;a nose fuze assembly disposed at the forward end of the housing, wherein the nose fuze assembly includes a detonator;a cartridge case assembly disposed at the aft end of the housing, wherein the cartridge case assembly includes a propelling charge and a primer to ignite the propelling charge; andan explosive charge disposed between the nose fuze assembly and the cartridge case assembly, wherein the explosive charge has a weight that is greater than 50 grams;wherein the breaching device has a minimum effective range of 10 meterswherein the nose fuze assembly is point-initiating, andwherein the detonator detonates the explosive charge upon impact of the nose fuze assembly with a target. 11. The 40 mm grenade according to claim 10, wherein the explosive charge composition comprises an a insensitive explosive. 12. The 40 mm grenade according to claim 10, wherein the weight of the explosive charge is in a range of 50 grams to 300 grams. 13. The 40 mm grenade according to claim 12, wherein the weight of the explosive charge is in a range of 50 grams to 150 grams. 14. The 40 mm grenade according to claim 13, wherein the weight of the explosive charge is 150 grams. 15. The 40 mm grenade according to claim 10, wherein the grenade is a close-quarter offensive grenade with minimum fragments to reduce collateral damage. 16. The short-range, self-propelled, non-fragmenting, door-breaching 40mm grenade of claim 10, wherein the composite housing contains a plastic compounded with a high density metal powder. 17. A method of preparing the 40 mm grenade of claim 10, the method comprising the steps of: (a) filling a high-density, composite housing with an explosive charge;(b) assembling a cartridge case assembly to the aft end of the housing; and(c) assembling a nose fuze assembly to the forward end of the housing. 18. A method of breaching a target using the 40 mm grenade of claim 10, the method comprising the steps: (a) loading the 40 mm grenade into a low velocity, 40 mm grenade launcher; and(b) launching the 40 mm grenade to breach a barricade target.
