They are/were missions related to special unit offers which have since expired and so are no longer available. The two units re likely to be sold as premium units again before too long.

It is likey though that the dfa will get a boost and boom bus will get nerfed before it becomes an 'an everyone can have' unit as the dfa is a bit weak and really not very good and the boob bus is very strong in a not of scenarios making it vulnerable to people over using it.

I have the boom bus at r6 (they are awesome) but really haven't bothered with the dfa as their attacks aren't very good compared with other similar units e.g. The dragon.
