They aren't astartes, yet they wield the same weapons and they'd please female gamers : more space boobs can't be a bad thing ^^
Personally, I like to see the Sisters of Battle. It will be good to see the feminine side of the Warhammer universe.
first of all i know that no one said SoB are SM but best to give a explanation before some one does sister of battle are like space marines in some things but they are not the same. they are not genetically engineered like the space marine to be versatile in combat here is the difference in their primary armament Sororitas Power Armour - Commissioned by Goge Vandire, it is the only part of his legacy that was not removed along with his head. Created initially by the forges on Mars for the Adepta Sororitas, this lighter power armour provides excellent protection and increased strength with little to no reduction in movement speed or agility. Similar to the light power armour often used by many Inquisitors, the Sororitas Power Armour has an extended operating life. Sisters of Battle do not have the advanced Black Carapaceof the Adeptus Astartes, however, the Sisters are trained to use their power armour to its fullest. Hospitaller Carapace Armour - Often serving in combat zones, Sisters Hospitaller require more protection than other Non-militant Orders. The distinctive armour is a welcome sight to injured guardsmen and Acolytes alike, an angel of mercy sent by the God-Emperor himself. In addition to its protective qualities, the hooded habit is often coated in incense and unguents and the rest of the armour is sealed and treated against toxins. Bolt Pistol Godwyn-De'az Pattern Bolter - Designed specifically for the Adepta Sororitas, and blessed by the Canonesses of the Orders, these venerated weapons are presented to an Adepta Sororitas upon becoming a Battle Sister. The Sisterhood considers the venerated Godwyn-De'az bolt weapons heirlooms; each one carefully maintained by highly specialized servitors and trusted servants. This pattern bolter has great significance to the Adepta Sororitas, not only as a powerful weapon against the enemies of mankind, but also as a symbol of the Emperor's judgement and of the sisters personal connection to her faith Frag & Krak Grenades here is the difference of SM stranded bolter and SoB stranded bolter Godwyn-De'az Pattern - The Godwyn-De'az Pattern Bolter is the standard pattern of Bolter used by all of the Orders Militant of the Adepta Sororitas since their formation in the 36th Millennium. This pattern has been in use by the Sisters of Battle since that time because it remains more reliable and more potent than any other pattern of Bolter developed for use by the Sororitas. The Godwyn-De'az Pattern is designed to be used by a normal human and thus is much smaller than an Astartes Bolter. This pattern of Bolter is designed to make use of the Sarissa as an attachment. The Sarissa is a vicious, curved, bayonet-like blade that can transform the Godwyn-De'az Bolter into an effective close combat weapon even as it retains all of its ranged functionality. i could put the SM bolter information here but i am sure you know the difference(plus it's really long) but they do have Faith as a use full weapon/ability. but i am not sure if the Emperor /a part of his splinted souls or the collective psychic of the sisters of battle(much like the orks) is giving them this powers
I will give them all of my moneys to be recruited within the Ordo Malleus and become a grey knight! Nothing can compare to those nemesis weapons, and these heretics are everywhere!
