(can you see the individual in camouflage above?  If not, it's because the newly developed 
Habitat Camouflage™ patterns have made them almost impossible to see anyone wearing them) 
Before you watch the video, I thought I would help you better understand what camouflage is and what it is used for. Camouflage is the ability of creatures or persons to conceal themselves by exhibiting similar colors and patterns to their surroundings.
Natural camouflage occurs among many 
animals and 
birds, allowing them to escape predators, or to be unseen by their own prey.  For example, a grey 
squirrel in a habitat of 
granite slopes and scree can appear inconspicuous, or a 
flounder (flat 
fish) can appear almost invisible among the pebbles on the ocean floor.  There are even some animals, including 
chameleons and 
octopus, which can change their color to suit their environment.  
Evolutionists claim that animals have evolved camouflage colors and abilities as an adaptation to their habitat which provides for better survival.
Camouflage clothing is used within the 
military
to allow soldiers to be less visible to their enemy when maneuvering.  
Camouflage colors were rarely used before the twentieth century, but 
khaki uniforms were adopted as a camouflage strategy in the 
trench warfare of 
World War I.  By 
World War II, uniforms with printed camouflage patterns were being used by many armies.
The most common military camouflage consists of green, brown and black shapes, allowing soldiers to camouflage in 
forest surroundings.  Other variants are used for other terrains, such as beige camouflage for 
desert operations, and white camouflage for 
arctic conditions.
