This is the Group for all DoD sub-groups/clans. In order to join a DoD clan, you'll need to join a sub group first. There are many to choose from, and most are accepting new members. Serch groups, put in the filter "DoD" and select Playstation since you are on a PS4. Join as many groups as you'd like and when you find a place that you feel like you fit in, set it as your clan.
