The Atlantic traces the history of military disguise in the twentieth century, the breakthrough realization that pixelated, “digital”-looking camouflage patterns work better than the traditional swirly ones, and the future of making people undetectable to the human eye:
Modern military camouflage traces its origins to World War I, when the French army gathered a cadre of artists in three top-secret workshops near the western front. The blotchy smocks they created sparked the popular imagination. Camouflage was not issued widely, though, because of the high cost and low production capacity: every yard of camouflage was a hand-painted work of art.
U.S. marines in the Pacific wore industrially manufactured camouflage during World War II, but its use was limited in Europe because German paratroopers were known for their camouflage uniforms, and American officials didn’t want confusion to cause fratricide. Camo uniforms were more widely issued to U.S. troops in the early 1970s, when jungle prints provided immediate advantages in Vietnam.
