Yearly dues are set by the officers of the 18th Indiana Battery; current dues are $25. All funding for the Battery’s expenses, such as powder, primers, paint and upkeep of equipment comes from the member’s dues, donations, and fund raising activities.  Participation in the 18th Indiana Battery requires an application and liability waiver. Applicants will be interviewed and if accepted will be classified as a RECRUIT and must pass the training criteria to participate.  Recruits are orientated to safety aspects of firing Civil War era artillery. Recruits must become certified by the National Civil War Artillery Association by attending one of the regional schools held for this purpose. Members cannot hold active commissions or non-com status if they are recognized members of another like period organization, due to the conflict of interest. The battery also portrays the 1st Rockbridge Artillery. This was a premier Confederate Unit organized at Lexington Virginia. This ability to portray Union Artillery or Confederate Artillery enables diverse participation at events. Family members are encouraged to attend and become involved in Civil War activities.

The Battery is community oriented and welcomes the participation of historians and educators. The Organization educates the public in the use of Civil War artillery, military equipment, uniforms, and conduct. This is accomplished by holding seminars, attending Living History events specifically designed to feature the Civil War, participating in reenactments, that recreate and demonstrates artillery, and by performing public service events, designed to honor the men and women that fought in the Civil War.
