Will start going into details on the forces present within the sector.
*
Stevid PDF: Given that the Ecclesiarchy cannot maintain any "
men under arms" it instead uses the Orders Militant of the all-female Adepta Sororitas for it's military force. These 'Sisters of Battles' are the most visible form of the Sororitas and the Ecclesiarchy's military forces and are equipped along lines to the Space Marines.
On the other end of the spectrum is the Frateris Militia, zealots who form an unofficial military force whenever a War of Faith is called. Most are little more than a barely organized rabbles, others are a bit better and have been known to achieve courageous acts.
In between the two forces lies the Stevid PDF, or the
Stevidian Sororitas Militia as it is more commonly known. It is effectively an all-female PDF, organized and equipped along Imperial Guard for the sole purpose of defending the Cardinal World of Stevid. The Sororitas Militia has on occasion fought alongside the Sisters of Battle throughout the region and have been the main Imperial force fighting the soldiers of the Accord during the Siege of Stevid.
The Sororitas Militia wear standard Imperial Guard uniforms, though these are adorned with symbols of the Ecclesiarchy. Similar to the pic below (though the pic's not mine).
