1. A composite structure, comprising:
a protective structure comprising a plurality of ballistic layers arranged as a stack; and
an ancillary structure adjacent to the protective structure adapted to at least partly absorb a force acting on the protective structure,
wherein the ancillary structure comprises at least one first layer comprising an aerogel arranged to at least partly absorb the force acting on the protective structure; and
wherein a first part of each ballistic layer is moveable relative to at least one adjacent ballistic layer and wherein a second part of each ballistic layer is connected to at least one adjacent ballistic layer so as to restrict relative movement of a part of each of the adjacent ballistic layers such that the first part of the ballistic layer can move to a greater degree relative to the at least one adjacent ballistic layer compared to the second part.
