Battlefield - Season 3 - Eps 2: The Undeclared War
What starts as a ripple becomes a wave, and with the United States involvement in Vietnam, it began as a contingent of U.S. "military advisors" after the attack at Dien Bien Phu. From there it turned into "non-official combat missions," and finally, after an unprovoked torpedo attack by a North Vietnamese patrol boat against the unsuspecting U.S. destroyer Maddox, it became "The Undeclared War."
