Identified Galactic gamma-ray sources include so far a small population of binaries that portrays a valuable set of features, making of them excellent targets for the study of outflows in general as well as other physical ingredients that determine their broadband non-thermal spectral energy distributions, e.g. the particle acceleration, the gamma-ray attenuation, the complex hydrodynamical behaviour of accretion/ejection or colliding flows, etc. I briefly review here our knowledge aboutthem, with particular focus on their high-energy emission.
