A decoy for an infra-red radiation seeking device that comprises: a) an anchoring body; b) two or more bundles (37, 38) of pyrophoric elements; c) straps (34, 35) that bind at least two of the bundles (37, 38) to the anchoring body; and d) two or more pyrophoric bodies (39, 40), wherein each pyrophoric body (39, 40) heats up upon exposure to air and melts or burns at least one strap (34, 35) that binds at least one bundle (37, 38) to said anchoring body thereby causing said at least one strap (34, 35) to break or fail resulting in the sequential release of said at least two bundles (37, 38) from said anchoring body and from said decoy after said decoy has been released from a target, wherein: (i) said two or more bundles (37, 38) of pyrophoric elements (39, 40) comprise a first bundle and a second bundle that are bound to said anchoring body by said straps (34, 35); and (ii) said first bundle is released from said decoy before said second bundle and said first bundle is released from said decoy at a position that is closer to said target than the position at which said second bundle is released from said decoy, further wherein; (a) each of the bundles (37, 38) forms a cloud of pyrophoric elements shortly after release from the decoy and said cloud of pyrophoric elements produce infra-red radiation; and (b) at least some of the pyrophoric elements comprise a pyrophoric coating on a supporting body, said pyrophoric coating containing at least one pyrophoric powder and a binder, characterized in that at least one of said pyrophoric bodies (39, 40) is a thin wafer or foil that is located on the upper surface of one of said bundles (37, 38) of pyrophoric elements and in contact with or located close to said at least one strap (34, 35) that binds the bundle (37, 38) to the anchoring body. a) an anchoring body; b) two or more bundles (37, 38) of pyrophoric elements; c) straps (34, 35) that bind at least two of the bundles (37, 38) to the anchoring body; and d) two or more pyrophoric bodies (39, 40), wherein each pyrophoric body (39, 40) heats up upon exposure to air and melts or burns at least one strap (34, 35) that binds at least one bundle (37, 38) to said anchoring body thereby causing said at least one strap (34, 35) to break or fail resulting in the sequential release of said at least two bundles (37, 38) from said anchoring body and from said decoy after said decoy has been released from a target, wherein: (i) said two or more bundles (37, 38) of pyrophoric elements (39, 40) comprise a first bundle and a second bundle that are bound to said anchoring body by said straps (34, 35); and (ii) said first bundle is released from said decoy before said second bundle and said first bundle is released from said decoy at a position that is closer to said target than the position at which said second bundle is released from said decoy, further wherein; (a) each of the bundles (37, 38) forms a cloud of pyrophoric elements shortly after release from the decoy and said cloud of pyrophoric elements produce infra-red radiation; and (b) at least some of the pyrophoric elements comprise a pyrophoric coating on a supporting body, said pyrophoric coating containing at least one pyrophoric powder and a binder, characterized in that at least one of said pyrophoric bodies (39, 40) is a thin wafer or foil that is located on the upper surface of one of said bundles (37, 38) of pyrophoric elements and in contact with or located close to said at least one strap (34, 35) that binds the bundle (37, 38) to the anchoring body. (i) said two or more bundles (37, 38) of pyrophoric elements (39, 40) comprise a first bundle and a second bundle that are bound to said anchoring body by said straps (34, 35); and (ii) said first bundle is released from said decoy before said second bundle and said first bundle is released from said decoy at a position that is closer to said target than the position at which said second bundle is released from said decoy, further wherein; (a) each of the bundles (37, 38) forms a cloud of pyrophoric elements shortly after release from the decoy and said cloud of pyrophoric elements produce infra-red radiation; and (b) at least some of the pyrophoric elements comprise a pyrophoric coating on a supporting body, said pyrophoric coating containing at least one pyrophoric powder and a binder, (a) each of the bundles (37, 38) forms a cloud of pyrophoric elements shortly after release from the decoy and said cloud of pyrophoric elements produce infra-red radiation; and (b) at least some of the pyrophoric elements comprise a pyrophoric coating on a supporting body, said pyrophoric coating containing at least one pyrophoric powder and a binder,
