Top critical review
Mindless fun at first, but weird overtones.

This review is for the series so far. (I see the 5th book is coming up) It is a very good read if all you want is just some "shoot 'em up" fun. The Smith girls (or Supertwins as I think of them) Have wandered far into the Mary Sue world. No matter what they do, they are the best. Come on. Infantry Officer/Naval Officer/Helicopter Pilot/Armor Officer.... The list goes on. Sorry, but any competent officers would have long spoke to the civilian authority and had the girls (and they are 14 and 15) regulated to, at best, training positions. They are constantly used to push other, better qualified adults out of positions where convenient plot holes swallow them up and regulate them to second tier positions (if that). As a former Infantry and later Armor NCO, I have had some experience in this world. I guarantee that no situation would call for placing children (even Mary Sue's) in a command position while professional, trained adults were available. But, the author has apparently decided to indulge some desire to have uberchildren be the focus of the series. My only recommendation would be to give some of the other characters some development, because at this point your focus is beginning to look like an uncomfortable fetish for underage girls.
