Soldiers operating in dusty conditions are often surrounded in a localised cloud when they fire their weapons.
This is caused by the various spherical shockwaves created as high velocity rounds leave a weapon and which then brush across the ground and generate clouds of dirt. The effects are that a camouflaged individual can be spotted by the puffs of dust he is stirring up and also that his own view of the enemy is obscured.
Today’s invention is a camouflaged, foil-lined sleeping bag which is placed lengthways in front of foxhole after filling with earth.
This acts to contain, refract and disperse the lower half of a shockwave before it can interact with dust on the ground near the the firing emplacement. It also acts as a barrier through which any ground dust will have trouble rising.
