Abstract: Future gamma-ray survey instruments, such as newASTROGAM and AMEGO-X, willsignificantly improve previous and current all-sky surveys at MeV energies. Inthis paper we discuss the continuum emission from the Milky Way, two prominentlarge extended sources, the Fermi bubbles and Loop I, and the extragalacticgamma-ray background. We highlight the importance of measurements in the MeV toGeV energy range for understanding CR production and propagation in the Galaxy,for the determination of the nature of the Fermi bubbles and Loop I, and forexploring the origin of the extragalactic gamma-ray background.
