I will present recent results from analysis of APOGEE/Gaia data for stellar populations in the Galactic halo, disk, and bulge, leading to constraints on the contribution of dwarf galaxies and globular clusters to the stellar content of the Milky Way halo. Interpretation of the extant data in light of cosmological numerical simulations suggests that the Milky Way has been subject to an unusually intense accretion history at z >~ 1.5. I will conclude by presenting recent preliminary results of the analysis of the latest (DR16) APOGEE data on the Gaia-Enceladus/Sausage system.
