This regulation provides standardized procedures for units or activities of one Service to obtain routine retail munitions support from another Service and immediate emergency retail munitions in direct support during combat operations from another Service when Service stocks have been depleted and normal resupply will not provide adequate or timely support. These procedures are applicable for request, issue, receipt, reimbursement, and documentation of routine and immediate emergency munitions support during Joint combat and training operations. The objective is to establish the simplest possible procedures to ensure the support of common levels of support for peacetime operations and the emergency exchange of common conventional munitions between Service components in Joint operations under wartime and/or contingency conditions.
