. Four were officially "organized" and remained so until September 1928, when all 31 were demobilized. Six of the other school groups were organized at some point during this period, four of which were on organized status on February 15, 1925. By the Army's rules of unit organization, the headquarters of a National Guard division could not stand up until at least 75 percent of its subordinate units had been Federally recognized. By the end of 1924, 13 of the 18 National Guard division headquarters (under which divisional air services were organized) had been initiated, after which reduced Army budgets resulted in a two-year suspension of Federal recognition of new units. National Guard aviation had 14 observation squadrons on February 15, 1925, in contrast to the Organized Reserve, which had 73 pursuit squadrons, 21 attack squadrons, and 18 observation squadrons assigned to its groups. However, in keeping with then-current legislation, National Guard units were allowed full manning (although at the time of mobilization for World War II the Guard as a whole was only at 50% strength), while O.R. units could have 100% of their authorized officer complements but no more than 33% of their enlisted strength, thus keeping most (including aviation squadrons) in a largely "on paper only" condition.
