  We study the pointwise (in the space and time variables) behavior of the
linearized Landau equation for hard and moderately soft potentials. The
solution has very clear description in the $(x,t)-$variables, including large
time behavior and asymptotic behavior. More precisely, we obtain the pointwise
fluid structure inside finite Mach number region, and exponential or
sub-exponential decay, depending on interactions between particles, in the
space variable outside finite Mach number region. The spectrum analysis,
regularization effect and refined weighted energy estimate play important roles
in this paper.
