I think tacticals will work surprisingly well, just the opposite of using tanks without air support. The world maybe horrified at seeing a couple nukes blowing in the middle of a field, but tactics could end using very effectively a bomb that can clean a couple of square km. in one sweep. The low-yield thing just add an icing to the cake; you can swifly move ahead your own army almost just after the nuke has went off, without waiting for a deadly fallout ends in a couple of days. And think about this: the enemy has no nukes and there's no way to stop the nukes. The battlefield has not seen this kind of radical strategic advantage since the invention of the tank.
