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 nonlinearities.
