  A large number of new black widow and redback energetic millisecond pulsars
with irradiated stellar companions have been discovered through radio searches
of unidentified \emph{Fermi} sources. We construct a 3D emission model of these
systems to predict the high-energy emission components from particles
accelerated to several TeV in the intrabinary shocks, and its predicted
modulation at the binary orbital period. Synchrotron emission is expected at
X-ray energies and such modulated emission has already been detected by
\emph{Chandra} and \emph{XMM-Newton} in some systems. Synchrotron and inverse
Compton emission from relativistic particles in the pulsar wind and intrabinary
shock can probe the unknown physics of pulsar winds and relativistic shock
acceleration in these compact binaries. Orbitally-modulated emission in the GeV
and TeV bands may be detectable under some favorable conditions.
