This catalog, "Grounds Munitions," supports Air Force Policy Directive (AFPD) 21-2, Non-nuclear and Nuclear Munitions, and is used in concert with Air Force Catalog (AFCAT) 21-209, Volume 2, Demolition Munitions. This publication is the primary munitions authorization source that units and command functional areas use to forecast ground munitions needs. Units and command functional areas must use AFCAT 21-209, Volume 2, when forecasting demolition munitions needs (i.e. blasting caps, demolition blocks, dynamite, etc.). This catalog contains operational and training munitions authorizations and explains how these authorizations are established, reviewed and changed. Justification referenced in other Air Force and or major command (MAJCOM) directives listing munitions requirements will be provided to the appropriate authority, if applicable. It provides general information on establishing, changing and estimating operational and training munitions authorizations; explains how to forecast proper category codes, maintain expenditure data and provides special instructions for munitions authorizations; provides munitions authorizations for training, exercises, evaluations and competitions; and provides munitions authorizations for peacetime security, war and contingency operations, and mobility.
