The implementation of an all-volunteer force in 1974 sparked academic inter
est in U,S. Army recruiting, During the past three decades Moskos's (1977)
Institution/ Occupation (I/O) thesis has dominated this literature. Moskos
held that the U.S. Army was becoming less of an institution and more of an
occupation. He warned about the danger of offering monetary incentives for
enlistment which, he believed, threatened to transform a patriotic duty int
o a mere job and might also undermine motivation to fight during wartime, T
his study examines recruiting theme trends through an analysis of recruitme
nt posters from 1915 to 1953. (In a companion article, we extend the examin
ation from 1954 to 1990.) Findings indicate that the I/O thesis was not bor
ne out (Janowitz 1977) and that military changes, including the emergence o
f an elite military culture, influenced recruitment themes.
