In what way can NGO's contribute to the European Security and Defence Policy?

I thank you for the opportunity to clear up the
question, from the point of view of a German relief organization, in what way NGOs can contribute to the European Security and Defence
Policy.
I do so from the perspective of the Johanniter-
Unfall-Hilfe, which operates on both the national
and international level, but I hope that I can also
speak for the other diversified relief organizations in Germany that have a similar structure.
