January 28 – March 6

Operation Masher was a combined U.S., South Vietnamese (ARVN), and Korean (ROKA) operation in Binh Dinh province. The name "Operation Masher" was changed to "Operation White Wing", because Masher was deemed too crude for 'nation-building' by the White House. Masher failed to result in any decisive victories by the allies, but temporarily disrupted NVA/VC control of the rural areas of the province. Masher and subsequent operations in Binh Dinh created large numbers of refugees who fled their homes to escape the fighting.^[13]

McNamara continued: "enemy...forces...are larger; terrorist and sabotage have increased in scope and intensity; more railroads and highways cut; the rice crop expected to come to market is smaller; we control little, if any, more of the population...in the countryside, the enemy almost completely controls the night."^[27]
