It's about the Tiger Stripe Uniform used in the Vietnam War that's featured by Coffee or Die... "While jungle green fatigues were the standard issue uniform for American GIs deployed to Vietnam, special operations soldiers generally preferred more unconventional combat attire. Members of SEAL Team 1, for example, were known to sometimes patrol in blue jeans and boonie hats. SEAL Team 2, on the other hand, adopted the fashion of their South Vietnamese counterparts and clad themselves in tiger stripe camouflage."
