What I understand is the tactical box is 3 sprues 10 marines. All options represented for a full tactical squad. So heavy weapons and special weapons represented. Sgt options represented, with the exception the combiweapon is multipart, you can only build 1. No word on sternguard options like special bolters and the like. Hands are molded with the weapons, but not arms, however some weapon/arm combos must go together. No chapter specific icons present.
