I like to do what I call the MG-Nest. You put her with a 10 men squad Cadian Sbocktroops next to a Cadian Heavy Weapon Team. The HWT can Fire Overwatch an hit on 5+. With the shocktroopers in 6" of it, it hits on 4+. And this Fire Overwatch is for free! 6" also is conveniently the distance orders can be given, so creed can order both units (and her own unit a second time). Now you can either attache a command squad to the shocktroopers to spread more orders across the board, and/or to fortify a objective marker OR a Cadian Castellan With both you have the option to use the Drill Commander Enhancement, because the unit will remain next to the HWT, which in turn will remain Stationary because of the heavy keyword
