A garment assembly such as a uniform, a military uniform and a military combat uniform is presented. The garment assembly includes a helmet or head cover being cut from a fabric having a first camouflage pattern with a first set of intermixed colored blotches thereon. The colors of the first set of intermixed colored blotches being selected from a first group of colors including an Olive 527 color, a Dark Green 528 color, a Tan 525 color, a Brown 529 color, a Bark Brown 561 color and a Dark Cream 559 color. The uniform also includes a coat being configured to fit at least a portion of a human torso and a trouser configured to fit at least a portion of human legs, the coat and trouser each being cut from a fabric having a second camouflage pattern with a second set of intermixed colored blotches thereon, the colors of the second set of intermixed colored blotches being selected from a second group of colors comprising an Olive 527 color, a Dark Green 528 color, a Light Sage 560 color, a Tan 525 color, a Brown 529 color, a Bark Brown 561 color and a Dark Cream 559 color.

Disclosed is a masking material intended to be disseminated by an ammunition or a launcher to create a cloud that masks a target with respect to electromagnetic radiation in a given wavelengths range. This material contains at least one aluminium oxyhydroxide, such as boehmite or pseudoboehmite. Also disclosed is an ammunition enabling the dissemination of such masking material and the use of aluminium oxyhydroxide, such as boehmite or pseudoboehmite as a masking material that can be disseminated by an ammunition.

A concealment substrate manufacturing process begins by printing or painting a graphic design as camouflage on substrates like mesh-textured uniforms, military equipment, Mylar thermal blanket sheets, adhesive tapes, etc. The graphic design is uniquely generated from pseudo-random noise in four overlaying color pigments that each begin as a raster of randomly generated noise in a standardized tile size. E.g., gray, green, tan, and brown colors natural for concealment applications are each masked by two-tone image contrast rasters. The four results are mixed together in groups with a monochrome mixing mask to produce a whole tile. Such concealment camouflage tile conjoins seamlessly on-edge within other arrays of identical tiles. One variation adds a distorted-grid mesh-texture overly texture to the concealment camouflage, and even a faint “watermark” related to a commercial trademark.

A fabric (30) includes a first flexible fabric layer (32), having fabric emissivity properties in a visible radiation range that are selected so as to mimic ambient emissivity properties of a deployment environment of the fabric, and at least one second flexible fabric layer (34), which is joined to the first flexible fabric layer, and which is configured to scatter long-wave radiation that is incident on the fabric. The first and second flexible fabric layers are perforated by a non-uniform pattern of perforations (44) extending over at least a part of the fabric.

The present invention is relates uses of a lens sheet as a camouflaging agent in various applications. Various embodiments of a lens sheet assembly, methods of making the various embodiments of the lens sheet assembly and methods of using embodiments by placing the assembly between an object to be camouflaged and an observer are disclosed. Light from the object undergoes at least one of refraction and reflection such that the object is substantially disguised from the observer.

A camouflage pattern is provided that appears to have infinite focus and depth of field even at 100 percent size for the elements in the camouflage pattern. Generally, three-dimensional (3D) models of elements to be used in the camouflage pattern are captured or generated. The models are then arranged in a scene with a background (e.g., an infinite background) via 3D graphics editing programs such as is used to render computer generated graphics in video games and movies. A two-dimensional (2D) capture of the scene thus shows all visible surfaces of the elements in the scene in focus at all depths of field. The elements may or may not be shaded by one another from the perspective of the image capture location in the 3D environment.

An underwater acoustic deception system deceives a sensor installed on a threat existing in or on water by acoustic effect in order to protect ships from the threat. The underwater acoustic deception system is provided with a control device, a laser oscillator and emission optical system. The control device determines a focusing position to focus a laser beam (50) in water in order to generate bubbles (70) at a desired position with a desired scale and emission parameters of the laser beam (50). The laser oscillator generates the laser beam (50) configured to focus in water and generate bubbles. The emission optical system emits the generated laser beam (50) to the focusing position. The underwater acoustic deception system deceives an arbitrary sensor existing in the water by acoustic effect of the bubbles (70) on the surroundings.
