  We describe a very compact (0.9 m high, 0.4 m diameter, 40 kg) battery
operable neutron scatter camera designed for field deployment. Unlike most
other systems, the configuration of the sixteen liquid-scintillator detection
cells are arranged to provide omnidirectional (4{\pi}) imaging with sensitivity
comparable to a conventional two-plane system. Although designed primarily to
operate as a neutron scatter camera for localizing energetic neutron sources,
it also functions as a Compton camera for localizing gamma sources. In addition
to describing the radionuclide source localization capabilities of this system,
we demonstrate how it provides neutron spectra that can distinguish plutonium
metal from plutonium oxide sources, in addition to the easier task of
distinguishing AmBe from fission sources.
