This practice originally began in the early years of the war when U.S. advisers working with indigenous troops such as the Montagnards offered a small cash bounty for Vietcong troops killed. In order to collect, they had to present proof of the kill, and it was decided that an ear would suffice. Combat photographs and film footage of American troops committing these atrocities and wearing necklaces comprised of dozens of severed ears sparked cries of outrage back home in the States.
