oil spot approach
n.— «The South Vietnamese government’s primary task, before it can hope to move toward needed political, economic and social reforms, is to provide villages with maximum security from communist harassment. This is the key objective of a phase of the current military effort that’s been dubbed the “oil spot” approach.…The “oil spot” strategy—now being implemented in nine scattered locations—aims to keep troops in a particular community until an effective local self-defense militia has been trained.» —“U.S., South Vietnam Spur Propaganda Drive To Counter Viet Cong” by William Belcher in Saigon Wall Street Journal July 31, 1964.
