"Vietnam Casulaty Rates Dropped 37% After Cambodia Raid" by Benjamin F. Schemmer, Armed Forces Journal, January 18, 1971

This article explains that U.S. combat deaths in Vietnam dropped significantly in 1970,  with overall casualty rates falling compared to earlier in the war. The South Vietnamese Army began taking on more fighting, and American medical care saved more lives, so soldiers’ chances of survival improved greatly. However, American pilots continued to face high risks, with aircraft losses remaining heavy and accounting for a growing share of combat deaths.
