Service sources said the status of the Comanche armed reconnaissance helicopter-with deployment to come no earlier than 2008-was a factor in delaying aviation transformation. The Army does not have enough attack and reconnaissance aircraft to meet active and reserve requirements. Without the Comanche, the Army faced the prospect of under-resourcing aviation formations, possibly for as long as a decade. Active units, with some exceptions, would have 80 percent of requirement; reserve components would be filled at 60 percent or less.
