69th Dragoon Cluster, Beta Galaxy (Former Burrock Cluster)
133rd Hussar Cluster, Beta Galaxy (Former Burrock Cluster)
206th Hussar Cluster, Delta Galaxy (Former Burrock Cluster)

EDIT: That's two full Galaxies of Burrock warriors. Two clusters went to Epsilon, others patched up the holes.
EDIT: My bad, apparently I can't count! :D That would be 3 in Epsilon.
