Fleet Marine Force corpsmen are the first medical responders to treat casualties in the field. They carry an outdated bag of supplies called the surgical instrument and supply set. The purpose of this investigation is to develop an updated supply set for field corpsmen by linking each supply item to specific medical tasks conducted in the field, which then creates an audit trail. The review of medical supplies generated an updated list of supplies to be carried by corpsmen in a new medical module and a list of items that corpsmen can pull from the battalion aid station authorized medical allowance lists as needed. Items without a clinical requirement were not included. This improved set of supplies for corpsmen will greatly enhance treatment capability in the field. As technology and needs change, replacements, additions, and deletions of the items can easily be made.
