and (ii) a union having two sockets of the same size as said plug units, said union comprising: (a) an internal-external threaded section, said internal-external threaded section having an interior surface and an exterior surface, having internal threads extending substantially along the entire interior surface and external threads extending substantially along the entire exterior surface, an open end, defining a socket sized to accommodate any said plug unit, and a closed end having a flat surface, the exterior surface of the internal-external threaded section defining a larger plug having a larger diameter; (b) an internal-only threaded section having internal threads and an open end, defining a socket sized to accommodate any said plug unit, having an external body surface not larger than the larger diameter of said internal-external threaded section, and having a closed end having a flat surface extending beyond the external body surface and having a diameter larger than the larger diameter of said internal-external threaded section; and (c) an internally threaded collar having internal threads and a first open end defining a larger socket sized to accommodate the larger plug of said internal-external threaded section, and a second open end having a central opening of the same size as the larger diameter of said internal-external threaded section, and a circumferential solid projection adapted to make contact with the flat surface extending beyond the external body surface of said internal-only threaded section; where, in use, said internally threaded collar pushes said internal-only threaded section nominally downward while at the same time pulling said internal-external threaded section nominally upward, causing the two flat surfaces to be pressed together face to face; and where two pieces of tactical gear affixed one each to said plug units, when connected to the respective socket of said internal-external threaded section and said internal-only threaded section, removably connect one piece of tactical gear to the other. ### Claim 2 (depends on 1) The tactical-gear interconnection system apparatus of claim 1, where said plug units are added to tactical gear during the manufacturing of the tactical gear. ### Claim 3 (depends on 1) The tactical-gear interconnection system apparatus of claim 1, where said plug units are added to tactical gear by retrofitting. ### Claim 4 (depends on 1) The tactical-gear interconnection system apparatus of claim 1, where components of said union are made of electrically conductive material. ### Claim 5 (depends on 1) The tactical-gear interconnection system apparatus of claim 1, where components of said union are made of electrically non-conductive material. ### Claim 6 (depends on 1) The tactical-gear interconnection system apparatus of claim 1, where the orientation of the socket in said internal-external threaded section in relation to the socket in said internal-only threaded section is essentially a straight line, with the sockets facing essentially 180-degree opposite directions. ### Claim 7 (depends on 1) The tactical-gear interconnection system apparatus of claim 1, said union further comprising said internal-external threaded section and said internal-only threaded section having sockets sized to accommodate different-sized plug units. ### Claim 8 (depends on 1) The tactical-gear interconnection system apparatus of claim 1, where size of said plug units is 1-inch diameter. ### Claim 9 A tactical-gear interconnection system method for removably connecting a variety of pieces of tactical gear, comprising: (i) providing a tactical-gear interconnection system apparatus, comprising: (a) a plurality of plug units of the same size, affixed to tactical gear; and (b) a union having two sockets of the same size as said plug units, said union comprising: (1) an internal-external threaded section, said internal-external threaded section having an interior surface and an exterior surface, having internal threads extending substantially along the entire interior surface and external threads extending substantially along the entire exterior surface, an open end, defining a socket sized to accommodate any said plug unit, and a closed end having a flat surface, the exterior surface of the internal-external threaded section defining a larger plug having a larger diameter; (2) an internal-only threaded section having internal threads and an open end, defining a socket sized to accommodate any said plug unit, having an external body surface not larger than the larger diameter of said internal-external threaded section, and having a closed end having a flat surface extending beyond the external body surface and having a diameter larger than the larger diameter of said internal-external threaded section; and (3) an internally threaded collar having internal threads and a first open end defining a larger socket sized to accommodate the larger plug of said internal-external threaded section, and a second open end having a central opening of the same size as the larger diameter of said internal-external threaded section, and a circumferential solid projection adapted to make contact with the flat surface extending beyond the external body surface of said internal-only threaded section; where, in use, said internally threaded collar pushes said internal-only threaded section nominally downward while at the same time pulling said internal-external threaded section nominally upward, causing the two flat surfaces to be pressed together face to face; and where two pieces of tactical gear affixed one each to said plug units, when connected to the respective socket of said internal-external threaded section and said internal-only threaded section, removably connect one piece of tactical gear to the other; and (ii) using said tactical-gear interconnection system apparatus for removably connecting a variety of pieces of tactical gear. ### Claim 10 (depends on 9) The tactical-gear interconnection system method of claim 9, where said plug units are added to tactical gear during the manufacturing of the tactical gear. ### Claim 11 (depends on 9) The tactical-gear interconnection system method of claim 9, where said plug units are added to tactical gear by retrofitting. ### Claim 12 (depends on 9) The tactical-gear interconnection system method of claim 9, where components of said union are made of electrically conductive material. ### Claim 13 (depends on 9) The tactical-gear interconnection system method of claim 9, where components of said union are made of electrically non-conductive material. ### Claim 14 (depends on 9) The tactical-gear interconnection system method of claim 9, where the orientation of the socket in said internal-external threaded section in relation to the socket in said internal-only threaded section is essentially a straight line, with the sockets facing essentially 180-degree opposite directions. ### Claim 15 (depends on 9) The tactical-gear interconnection system method of claim 9, said union further comprising said internal-external threaded section and said internal-only threaded section having sockets sized to accommodate different-sized plug units. ### Claim 16 (depends on 9) The tactical-gear interconnection system method of claim 9, where size of said plug unit is 1-inch diameter.
