Indigenous troops in tiger-stripe camouflage fill their canteens from a U.S. Army water tanker at a remote firebase, a routine but essential task in the field. Forces like these, often Montagnard, Nung, or Hmong guerrillas, worked alongside MACV-SOG advisors on covert cross-border missions such as Operation Tailwind, providing the manpower and local knowledge that made such operations possible.
