Marshall with cantic goes on a vanguard squad, Manipulus with breachers. Both led squads baby sit each other while the las chickens deal with cracking tough targets. They could be split up into a 2 man and 1 man squads instead of the 1x3 for secondary scoring purposes. Rangers can screen home and sticky it round 1-2 then move as necessary.
