We consider the tunneling of a wave packet through a potential barrier which
is coupled to a nonintegrable classical system and study the interplay of
classical chaos and dissipation in the tunneling dynamics. We show that
chaos-assisted tunneling is further enhanced by dissipation, while tunneling is
suppressed by dissipation when the classical subsystem is regular.
