I've discovered the evil tactic built into the SSU forces: The Commissar squad's special order. For those who don't know, the squad can issue a special order during the Command Phase that removes the Reaction marker from every friendly unit in 12" of the command commissar. This, of course, simply encourages SSU lists to be chock-full of cheap units, because you WANT to get more special orders and go second. That way, you can have units fire at the enemy during the Command Phase, use the normal command squad's special command to double the suppression thus created on a single unit, and then the commissar squad removes the Reaction markers from all those squads that just acted.
I really have to compliment this, and give whoever designed this combination credit, because this encourages the creation of army lists that include more and more units, in order to generate more special orders each turn and suck up the fire directed at them from longer range, in order to close on the enemy and overwhelm them with, essentially, bravado. Very, very Russian/Chinese horde tactics. Well done, whoever came up with this!
