Prelude:
I was originally planning on only raising an 
Astra_Militarum force for 
Warhammer 40,000 (WH40K).
However, a few serendipitous events happened that motivated me to expand my force of common foot soldiers.
First, I read 
Faith & Fire, a novel about the 
Adepta_Sororitas (Sisters of Battle), or for us "cynical fans" 
Nuns with Guns.
I liked it so much, I read the sequel, 
Hammer & Anvil.
There's an additional novel and novella, compiled in an omnibus with the earlier books by 
James Swallow that I'm currently not in the mood to buy.
But shortly after reading the first books back-to-back, someone offered to sell his painted metal Sisters of Battle miniatures collection for such a great price I couldn't pass up the opportunity.  While I'm not in the mood to buy a book that I've essentially read half of already, I'm always in the mood to buy figures I don't have to paint.
Since this was two years ago, I'm afraid I can't remember the guy's name, nor what I actually paid for the figures.
Anyway, these figures dated back to WH40K 
2nd Edition.
The problem for me--and a considerable number of fans of the 
Naughty Nuns--was that we had rules for 6th, 7th and finally 
8th_edition.  None of which featured the Adepta Sororitas.  So folks had to make due with old models and old 
Codexes and wedge them into their games.
Then, amid much rumors and anticipation, the 
Sisters of Battle Army Set was released with 
much fanfare in December 2019.
While the new plastic models look stunning, I wasn't in the mood to add to my 
Mountain of Shame.
All I wanted was the codex and game accessories, which 
Games_Workshop (GW) assured it's long-suffering fans--
again, with much fanfare--that additional material would be available shortly after the New Year.
Fortunately, GW made good on their promise and I scarfed-up the codex, data cards and dice.
Now that I have all the necessary 8th Edition 
Crunch to run an Adepta Sororitas task force (in)competently, and 
Fluff to maintain my 
geek cred; I can finally post a decent Pass in Review.
Review:
Somewhere in the 
Sector Fronteris...
...an Adepta Sororitas task force assembles.
The first vehicle to approach the apparently abandoned settlement is a 
Chimera armored personnel carrier (APC).
This vehicle is actually part of my 
Inquisitor Retinue, but since the color scheme is about the same does double-duty, serving with both the 
Inquisition (a.k.a. 
The Emperor's Pet Psychopaths) and the Adepta Sororitas.
I'm including this vehicle because it is part of the Sisters' order of battle, according to the 
Witch_Hunters Codex (3rd_Edition), but seems to have been dropped by this edition.  I figure I could use the stats from the Astra Militarum's 
Splatbook.
Next in the advance column is 
Rhino...
...followed by an 
Immolator.
The Adepta Sororitas' vehicle laager-up around the abandoned settlement.
My figures were painted based on the 
Order_of_Our_Martyred_Lady, in honor of 
Saint Katherine, the founder of their order and probably the most commonly fielded of the 
Orders Militant.
Since these figures are dressed mostly in black I decided to remove the settlement buildings for a clearer image of the miniatures.

| (1st Battle Sisters Squad) | 
Adepta Sororitas' task forces are known as "Missions." These are considered the smallest organizational units capable of independent action and form the military arm of the 
Adeptus Ministorum, a.k.a. The 
Ecclesiarchy.  In addition to forming the main militant arm of the 
Church Militant, the Adepta Sororitas also works closely with the Inquisition’s 
Ordo Hereticus.
Note on higher echelons:  Two or more Missions form a Commandery, two or more Commanderies for a Preceptory, while the various Orders are divided between two Convents—Convent Sanctorum and Convent Prioris.
My particular Mission consists of two squads of Battle Sisters, each armed with an assortment of 
Bolters,
Flamers, 
/Storm_Bolters, and 
Meltaguns, with one sister bearing the 
Simulacrum_Imperialis and led by a power sword-wielding 
Sister_Superior.

| (2nd Battle Sisters Squad) | 
With a little finagling I might be able to select some figures from the two Battle Sisters Squads and form a single 
Celestian squad instead.
The Battle Sisters/Celestian Squads will need close-assault specialists or fire support.  And that's where the 
Dominion and 
Retributor squads come-in.
|  | 
| (Dominion or Retributor?) | 
From what I can gather, the four figures pictured above could form either a Dominion or Retributor Squad.  I'll just need to clarify what they are at the start of any game.
If the Adepta Sororitas can be considered religious zealots, then the 
Sisters_Repentia are fanatics.  These women seek atonement for their real, or perceived sins and form the Sororitas' 
suicide squads.
Here's my full squad of Repentias:
Since the picture looks a bit crowded, I split the squad in half for a better view of the 
Chainsword-wielding Repentias, driven-on by their 
Mistress:
My Adepta Sororitas Mission includes two special characters.
First, is the shotgun-wielding preacher, 
Uriah Jacobus, bearing the 
Banner of Sanctity:
Second, and commander of my Adepta Sororitas Mission, is none other than 
Canoness Veridyan, the iconic poster-girl for the Sisters of Battle:
While the Adepta Sororitas aren’t genetically 
mutated enhanced like the Space Marines.  Despite this, they can count on divine intervention in the form a 
living saint:
 Saint Celestine.
Another version of Saint Celestine and her attendant 
Geminae Superia:
Here’s my entire Adepta Sororitas Mission, or as many as I could squeeze into one image, minus the three transports shown earlier:
Overall I’m very happy with my Sisters of Battle collection.  While I stated earlier I wasn’t planning on adding to my Mountain of Shame, I could use a few 
Hopitallers to act as the Mission’s 
medics or 
field chirurgeons.  So I hope there’ll be some available separately that I could purchase without having to get an entire starter kit.
 
Since this is an older set of metal miniatures, some figures, especially the Repentias, required some touch-up paint work.  I also added the sand flocking to the black bases, minus the flying figures of Saint Celestine and her Geminae Superia.
I'm sure the new plastic models will be more detailed.  But for the most part, I like the weight and feel of metal miniatures.  I've had to add washers underneath the bases of my WH40K plastic figures because they're too light and tip over easy.  My metal ones can too, especially if their pose is too extreme, like with my Repentias.
