It may comprise a container (104) for holding an obscuration cloud generating canister (110), wherein a composition for forming the obscuration cloud is emitted from the obscuration cloud generating canister (110) in response to activating the obscuration cloud generating canister (110). It may further comprise a housing (101) having a frame (103) wherein the container (101) is removably held inside the frame (103). The housing (101) has an opening (105) and a door (102), the door (102) being movable between a closed state for covering the opening (105) and an open state for emission of the composition from the device (100) via the opening (105). The opening (105) is shaped and sized to allow the container (104) to be extracted from the housing (101) through the opening (105) when the door (102) is open to replace the obscuration cloud generating canister (110). ## Claims ### Claim 1 An assembly for an obscuration cloud generating device for being removably held within a housing of the obscuration cloud device, the assembly comprising: an obscuration cloud generating canister, wherein a composition emitted from the obscuration cloud generating canister is emitted via an outlet of the assembly in a defined direction that is off a longitudinal axis of the obscuration cloud generating canister; and at least one guiding member of the assembly for positioning the assembly in a specific angular orientation within and with respect to the housing, so the housing has a fixed positional relationship with respect to the outlet to fix an angle of emission with respect to the housing. ### Claim 2 (depends on 1) The assembly of claim 1, wherein the at least one guiding member includes at least two guiding members, each having different dimensions, each corresponding to at least two housing guiding members having corresponding dimensions. ### Claim 3 (depends on 1) The assembly according to claim 1 wherein the assembly further comprises a container sized and shaped to hold the obscuration cloud generating canister, and the at least one guiding member is on the container. ### Claim 4 (depends on 3) The assembly of claim 3, wherein the container includes a first part and a second part, wherein the first and second parts engage with each other to hold the obscuration cloud generating canister therebetween, and the first and second parts are keyed to predefine an angular orientation of the first part with respect to the second part. ### Claim 5 (depends on 4) The assembly of claim 4, wherein the container further includes a third part that is attachable to the second part, wherein the second and third parts are keyed to predefine an angular orientation of the second part with respect to the third part. ### Claim 6 (depends on 3) The assembly of claim 3, wherein the container includes an alignment element for holding the obscuration cloud generating canister in a specific angular orientation inside the container. ### Claim 7 (depends on 6) The assembly of claim 6, wherein the first part includes the alignment element and the second part includes at least one of the at least one guiding members. ### Claim 8 (depends on 7) The assembly of claim 7, wherein the first part includes the alignment element and the third part includes at least one of the at least one guiding members. ### Claim 9 (depends on 5) The assembly of claim 5, wherein the third part having terminals for conveying power to the obscuration cloud generating canister. ### Claim 10 (depends on 4) The assembly of claim 4, wherein the first and second parts having cylindrical shape. ### Claim 11 (depends on 6) The assembly of claim 6, wherein the alignment element engages with a corresponding alignment member on the obscuration cloud generating canister. ### Claim 12 (depends on 3) The assembly of claim 3, wherein the container is removably held inside the housing by a quick release mechanism. ### Claim 13 (depends on 12) The assembly of claim 12 wherein the quick release mechanism comprising at least one member on the container for selectively engaging or disengaging from a corresponding member on the housing to respectively secure the container in the housing or enable withdrawal of the container from the housing. ### Claim 14 (depends on 12) The assembly of claim 12, wherein the quick release mechanism comprising a handle. ### Claim 15 (depends on 12) The assembly of claim 12, wherein at least some parts of the quick release mechanism are rotationally movable with respect to the at least one guiding member for the removal. ### Claim 16 A system, comprising: an obscuration cloud generation device having a housing; and an assembly for being removably held within the housing of the obscuration cloud device, the assembly comprising: an obscuration cloud generating canister, wherein a composition emitted from the obscuration cloud generating canister is emitted via an outlet of the assembly in a defined direction that is off a longitudinal axis of the obscuration cloud generating canister; and at least one guiding member of the assembly for positioning the assembly in a specific angular orientation within and with respect to the housing, so the housing has a fixed positional relationship with respect to the outlet to fix an angle of emission with respect to the housing. ### Claim 17 (depends on 16) The system of claim 16, wherein the assembly further comprises a container sized and shaped to hold the obscuration cloud generating canister, and the at least one guiding member is on the container; wherein the quick release mechanism comprising a handle; wherein the handle having a closed position wherein the handle is laid inside a recess on the container, and an open position wherein a force may be applied to turn the handle and another force may be applied to pull the handle for releasing the container from the housing. ### Claim 18 (depends on 16) The system of claim 16, wherein the at least one guiding member includes at least two guiding members, each having different dimensions, each corresponding to at least two housing guiding members having corresponding dimensions. ### Claim 19 (depends on 16) The system of claim 16, wherein the at least one guiding member includes at least two guiding members, each having different dimensions, each corresponding to at least two housing guiding members having corresponding dimensions; wherein the container is removably held inside the housing by a quick release mechanism. ### Claim 20 (depends on 16) The system of claim 16, wherein the at least one guiding member includes at least two guiding members, each having different dimensions, each corresponding to at least two housing guiding members having corresponding dimensions; wherein the container is removably held inside the housing by a quick release mechanism; wherein the quick release mechanism comprising at least one member on the container for selectively engaging or disengaging from a corresponding member on the housing to respectively secure the container in the housing or enable withdrawal of the container from the housing.
