If you are a serving member or retired from the Royal Artillery then membership is automatic. The same applies to spouses/partners.
To formalise the process you will need to complete an Application for Registration which basically lets the RAA know that you are an active member.
You can download the form from the link below.
Once completed you can hand it into the branch. If you may have difficulties completing the registration form then don't worry, someone from the branch will help you complete the form and sent off.
Membership for those who have not served in the Royal Artillery
You are welcome to apply for branch membership. The process is the same as above.
