re: They used the best pun in the title of this piece
"they are, in a sense, variations on the camouflage uniforms and face paint American soldiers use to bolster their sense of invisibility (and, therefore, immunity) during combat."
Quite the opposite, camouflage doen't give a "sense of invisibility" it makes it harder for enemy to spot at a distance. It's more like the red coats of British and other colonial powers- they were brightly colored in order to cause fear in the enemy.
