Here we go. Another 5 man tactical Support squad. After a recent conversation with FW staff; sergeants also get a Flamer in a tactical support squad so they too can carry a special weapon. It is something they want to address eventually as the book is a bit unclear.
Anyway. Trust an Iron Warrior to pack a bigger gun. These weapons look mean and will be great against non marine targets due to the amount of shots they have. Sadly their stopping power against Legionnaires is slightly lacking. Ho Hum.
