We have demonstrated numerically
 that new families of spatiotemporal dissipative optical bullets
 which include self-trapped necklace-ring, ring-vortex solitons, uniform ring beams, spherical
 and rhombic distributions of light bullets, fundamental and
 cluster solitons are possible in the higher-order
 (3+1)-dimensional cubic-quintic-septic complex Ginzburg-Landau
 [(3+1)D CQS-CGL] equation with higher-order effects such as
 stimulated Raman scattering, self-steepening and third-, fourth-,
 fifth- and sixth-order dispersion terms. These solutions remain
 localized and can be self-trapped over a huge propagation
 distance, even in the presence of random perturbations, due to the
 combined influence of dispersion, diffraction, gain, loss,
 spectral filtering, Raman effect and cubic-quintic-septic
