Returning to my Grand Army idea it did not feel right to not include my Adepta Sororitas, Order of the Valorous Heart. They way I feel it would be the Sisters as the boots on Ground Force requesting aid and holding ground. Storm Troopers performing recon and scout missions. Grey Knights taking ground and performing the majority of the heavy lifting. Sisters of Silence as needed. And the Inquisition assisting all forces. 

Normally I would have my forces here but I want my Sisters to represent a Commandery so just under 200 Sisters

I may have to add Pewter sisters to the forces....maybe
