  This work intends to provide a brief summary of some of the Galactic science
issues for the next generation of very high energy (VHE) instruments. The
latter is here generically understood, as an instrument or set of instruments
providing about one order of magnitude more sensitivity at its central energy
(at about 1 TeV), but extending the observational window to have a real
broadband capability (from a few tens of GeV up to tens of TeV); exceeding at
low energies the current VHE threshold for observations set by MAGIC as well as
the few-tens-of-GeV sensitivity set by Fermi. Science topics regarding
populations of emitters, pulsars and their nebula, binaries, supernova
remnants, stars, and their associations, are discussed.
