  We present a covariant, supersymmetric and kappa-symmetric action for
non-Abelian multiwave system (nAmW) in D=3 AdS superspace. Its flat superspace
limit provides a simplest counterpart of the recently proposed action for 11
dimensional system of N nearly coincident M-waves (multiple M0-branes), which
is presently known for the case of flat target superspace only.
