Quartermaster is an officer of a group, a deputy of the Exchequer, that is responsible for the storage and maintenance of physical assets of the group. As an officer, the Quartermaster must be a paid member.

The Quartermaster is responsible for:

• Maintaining an inventory and submitting it to the Exchequer at the end of every year
• Maintaining an accounting of the disposition of items in the inventory (losses, acquisitions)
• Checking equipment out to members for use
• Checking equipment back into storage when returned, ensuring that all items are returned in good shape

The Quartermaster position is a low commitment position with brief periods of activity. While some groups may be moving to third party storage facilities, traditionally, the inventory is stored at the Quartermaster's home.
