That's not true. Modern body armor was available in Vietnam [1], and was the result of an ARPA research program. It was expensive and rarely issued though until later, but the technology (boron-carbide plates) is similar to what is used today. You're thinking of Richard Davis, the inventor of the police-issued Kevlar vest. He invented it in the mid 1970s, after getting in a gunfight while working as a pizza delivery driver.
