This report describes research conducted to improve the Army's ability to use recruiting resources and enlistment eligibility policies effectively to meet enlisted accession requirements under good, average, and bad recruiting conditions. We consider the cost of meeting accession requirements when an optimal mix of television advertising and enlistment incentives is feasible (the baseline strategy) or when an incentive-centric strategy — which favors incentives over other resources due to incentives' faster rate of increasing recruits — is required.
