Operation Massachusetts Striker was a joint U.S. Army and Army of the Republic of Vietnam (ARVN) military operation during the Vietnam War designed to keep pressure on the People's Army of Vietnam (PAVN) units in the southern A Sầu Valley and prevent them from mounting any attacks on the neighboring coastal provinces.
