The new organizational hierarchy thus contained the following levels : squadron, group, wing, air force, command.
In 1948, and afterward, the World War II wings were redesignated "divisions", and placed immediately below the numbered air forces in the organizational pyramid.
Because they were usually technical or highly specialized in nature, named divisions generally had a large number of personnel.
In Vietnam the USAF's 834th Air Division also had small Divisional lateral units called an "elements."
These usually consisted of a lt. col or major, E-6 or E-7, and one or two E-4 or E-5 AFSC 271XX to coordinate C-130, C-7A, and occasional C-123 traffic on unimproved airfields.
