  We study the smectic AC transition in anisotropic and uniaxial disordered
environments, e.g., aerogel with an external field. We find very strange
behavior of translational correlations: the low-temperature, lower-symmetry
Smectic C phase is itless translationally ordered than the it high-temperature,
higher-symmetry Smectic A phase, with short-ranged and algebraic translational
correlations, respectively. Specifically, the A and C phase belong to the
quasi-long-ranged translationally ordered " XY Bragg glass '' and short-ranged
translationally ordered " m=1 Bragg glass '' phase, respectively. The AC phase
transition itself belongs to a new universality class, whose fixed points and
exponents we find in a d=5-epsilon expansion.
