  We study numerically and analytically the behavior of classical Yang-Mills
color fields in a random one-dimensional potential described by the Anderson
model with disorder. Above a certain threshold the nonlinear interactions of
Yang-Mills fields lead to chaos and deconfinement of color wavepackets with
their subdiffusive spreading in space. The algebraic exponent of the second
moment growth in time is found to be in a range of 0.3 to 0.4. Below the
threshold color wavepackets remain confined even if a very slow spreading at
very long times is not excluded due to subtle nonlinear effects and the Arnold
diffusion for the case when initially color packets are located in a close
vicinity. In a case of large initial separation of color wavepackets they
remain well confined and localized in space. We also present comparison with
the behavior of the one-component field model of discrete Anderson nonlinear
Schr\"odinger equation with disorder.
