[2] After World War II he returned to West Point where he served as a Tactical Officer from 1946 to 1948.
With the publication of basic operational manuals, the 1st Brigade was able to standardize aviation operational procedures throughout Vietnam, establish training schools, enforce safety regulations, and in general more effectively manage the growing aviation assets.
In coordination with Major general William E. DePuy who then commanded the 1st Infantry Division, Seneff began a test period to determine the most satisfactory means of supporting a line infantry division with separate aviation elements.
While considerable work had been done in this area during 1965, it had grown in different directions depending on the unit supported and the aviation assets available.
From March 1969 he served as operations officer at United States Strike Command and as deputy director of Modern Army Selected Systems Test Evaluation and Review project ("Project MASSTER").
