You know, I think it is important to remember that they stole a whole bunch of them mechs and explicitly said they had to move ahead of schedule. It is quite possible their original intent was to make a much bigger splash by combining the Grimm attack with a coordinated mechanized assault, but because of Team RWBY their plans went awry. A Grimm assault may have still served their purposes to an extent, but they still managed to achieve far less than intended. Suppose they are now on Plan B.
