  We present an extension of the Arnold-Moore-Yaffe kinetic equations for jet
energy loss to NLO in the strong coupling constant. A novel aspect of the NLO
analysis is a consistent description of wider-angle bremsstrahlung
(semi-collinear emissions), which smoothly interpolates between 2<->2
scattering and collinear bremsstrahlung. We describe how many of the
ingredients of the NLO transport equations (such as the drag coefficient) can
be expressed in terms of Wilson line operators and can be computed using a
Euclidean formalism or sum rules, both motivated by the analytic properties of
amplitudes at light-like separations. We conclude with an outlook on the
computation of the shear viscosity at NLO.
