Weapons

Soulsword
"You shall make your pledges of peace, faith, and war upon this sacred Soulsword.  This hallowed weapon, forged from the shard of the great Demon Slayer, legendary blade of Narsill the Incarnate, has fought in the hand of this Chapter's greatest veterans.  It has had the honor of slaying alien beast, monsters, heretics, and demons alike.  One day, one chosen among you might become worthy enough to wield it.  Until then, thou shalt kneel before it!"
-Speech of the Soulsword
Soulswords are considered to be by far the greatest achievement of humanity.  Undoubtedly the first Soulsword was none other than the fabled Demon Slayer itself, the legendary holy blade of Narsill the Incarnate which pierced the Heart of Zarkros at least ten millennia ago on Terra, signifying the beginning of the First Age of Mankind.  That same sword has since become a broken blade; shattered into thousands of fragments upon the conclusion of the Cain Sundering, that dark time when heresy became rampant upon Humanity and led to the untimely death of Narsill the Incarnate and the reforging of the Fallen Kingdoms of Man.  To preserve the sword and to give faith to those who would otherwise be hopeless in the face of defeat, the fragments were sent to the Ecclesiarchy and the Technopathica, where they were used to forge the legendary Soulswords themselves.
A Soulsword, when first drawn, appears to be nothing but a single, empty hilt of what would otherwise be a magnificent blade.  This is by far not the case, as the design ensures that the shard itself is kept intact and protected when not in use, as well as preserve the blade's own portability.  The actual blade in this state comes in the form of a very compact metallic liquid that resides inside of the hilt under extreme pressure, with the shard in the center of this liquid.  The blade is activated at the touch of a button, which causes a force field to instantly encompass the exact edge of this blade when it reaches full length.  The compact liquid then spurts forth evenly, glowing with extreme heat as it extends the entire length of the force field before the field's energy instantly cools it, creating a perfect blade.  The shard extends out to whatever piece of the original blade it once belonged, ranging anywhere from the base of the hilt to the very tip of the sword.  It is unknown how exactly it does this, though it is believed that perhaps the spirit of the original Demon Slayer still resides in each individual shard, giving the shards their ability to remember which part of the blade they once resided in.
All true Soulswords glow a bright blue upon their activation.  This is in part a combination of the force field, which still is in partial activation to ensure the blade's protection, and the actual shard itself, which extends its own glow throughout the metal of the blade.  The original Demon Slayer was heralded to glow a tremendously bright blue whenever demonic activity was rampant, and its surface became almost like pure light upon piercing the tainted flesh of anything heretical, be it demonic or otherwise.  When a Soulsword is in use, its very presence alone is enough to raise the morale of all who see it and believe in the power of the Maker.  Space Warriors who have otherwise fallen back to recover their losses will rush forward with renewed strength, Guardsmen will cast aside their fear and bring their weapons to bear, even Psykers, who would otherwise be far too withdrawn from the mental images and psychic screams of battle, will rise renewed in spirit and mind and return to the battlefield with purpose upon seeing the beautiful blade in its full glory.
When a Soulsword is in use, they tend to have varied effects depending upon the individual.  A single Soulsword, when used correctly, can function as any normal blade can save for a few differences.  The force field surrounding the blade acts as a hardener for the blade, ensuring that blows upon its surface that would otherwise shatter any normal melee weapon from the stress can be shrugged off as if it never happened.  The blade's also extreme sharpness ensures that even armor can be pierced by its slender grace.  If that weren't enough, to top it off every Soulsword with a shard of Demon Slayer gains the original's properties to a fraction, meaning that they can launch holy powers into an enemy and shatter their souls into oblivion.  This means that to any demon regardless of size or strength, a stab from Demon Slayer is guaranteed to be lethal, while heretics are forever marred by pain from the weapon's holy might.
Of course, not all Soulswords can have the honor of holding a shard of Demon Slayer within them.  Most, especially those used by standard churches as holy relics, are replicas that accomplish the same goals but do not nearly have as much holy power or standing as the true relics.  Given the fact that they are also rare and very precious relics, almost all Soulswords owned by Space Warriors are kept upon their headquarter worlds within their mighty Castle Cathedrals or Fortress Monasteries, only brought into battle in the direst of circumstances.  The original Prime 13 chapters each bear at least one Soulsword per company out of their standing in the past as legions and progenitor Chapters, though all other chapters are only allowed a single Soulsword, with some being unable to bear any at all.  It because of the rarity of these weapons that the Inquisition jealously guards the Soulswords of humanity, and often enough they send squadrons of Paladins, the holiest of all holy Space Warriors, to worlds once long lost to humanity in order to reacquire lost Soulswords from battlefields past, regardless of the danger to themselves or the rest of humankind.  If a single shard of Demon Slayer becomes corrupted, should the sword eventually become reforged the corruption would stain its own blade, and its power would forever be broken.

Assault Rifle
The Mark IV Standard Caliber Space Warrior Assault Rifle has been the chosen Space Warrior ranged weapon for the entire four thousand years of their existence.  A single Assault Rifle bears two important factors; versatility and brutality.  The simple box-like design of the rifle bears parts that can be interchangeable and easily replaceable.  The barrel can be lengthened for accuracy or shortened for the sake of bullet spread.  A single Assault Rifle bears two different forms of ammunition; the secondary ammunition, designed for convenience, is the same used by standard Guardsmen weaponry; designed to eliminate foes with lesser armor and defenses and be easily replaceable.  Their standard ammunition is a powerful assault round that is designed to pierce through ceramite and explode upon contact, peppering foes with miniature explosions that tear through organs and ruin muscle and bone.
The Assault Rifles can be reconfigured in a variety of ways to ensure maximum usage as well as for the convenience of mass production; it is far easier to create a massive amount of parts for a single chassis that can be interchangeable than to create multitudes of different guns that can do the same job.  Assault Rifles are also very heavy weapons; an average human will find difficulty picking them up and wielding them effectively without the aid of a stand.  The most common and popular conversions for an Assault Rifle includes a precision variant, a shotgun variant, and even a grenade launcher variant, ensuring that each chapter has maximum versatility per squadron without the reliance of specialized tactical squads such as Adamants or Assault Troopers.

Hellfire Pistol
The original design for the Mark VII Hellfire Personnel Weapon has been around far longer than its popular users have been.  Hellfires saw action during the great Reckoning Wars on Terra long ago, and their versatile and very effective design has seen their use for at least six thousand years.  What makes them so reliable is their combination of renowned accuracy, quick trigger, and the ability to load almost any kind of ammunition through the use of an adaptable cartridge inside the action, meaning that even modern ammunition of the 11th Millennium can be used by this antique design.
Hellfire Pistols are most widely used by individuals who prefer to use melee weapons.  This is because the Hellfire is an easy weapon to practice and get used to using in an individual's less dominant hand, primarily because the pistol is light, easy to manage, and accurate enough that even by pointing the weapon in the general direction of the foe a grazing blow is possible.  The pistol's primary use for said individuals is in the form of providing a ranged advantage under cover for those troops who are otherwise confined to close-quarters combat.
The side-effect to such an effective weapon being in existence for so long and in such quantity is that other races have jumped the bandwagon and learned how to make said weapons as well.  Orcs and several races in the Kingdoms of Flame in particular have discovered how to use the unique cartridge in the Hellfire Pistol's action in order to wrap around any ammunition, allowing for both groups the ability to salvage ammunition that is otherwise worthless on the battlefield when ammunition is running low.  As a result, the pistol has received an affectionate but otherwise appropriate nickname; the Weapons Whore.  Despite this, the Hellfire's assets far outweigh its liabilities, which is why it still remains the single most popular and most-used small-arms weapon in humanity's history.

Vulcan Hammer
Never has such a melee weapon been so feared by the enemies of man as the Vulcan Hammer.  Named after the man who designed the hammer, Vulcan de Leon – successor High Templar to the late Gabriel de Leon, the hammer is as every bit as formidable as its reputation describes it.  The weapon has earned its respect in the Kingdom of Men, and is used widespread by many different Space Warrior Chapters and their squadrons for the past 4,000 years since its forging.
The Vulcan Hammer is essentially a large block of metal; a foot long with a six inch width and height, built using several different pieces that are all kept clamped together using powerful and effective machinery.  The hammer is made out of several different metallic alloys that give it different unique purposes; mithril for the sake of sturdiness, ceramite for increased weight and resistance to extremes, and adamantium for the sake of indestructibility.  This combination of alloys gives the hammer a very dark, volcanic color.  The weapon as a whole weighs half a ton, designed only for the use of Space Warriors and their counterparts.
The usage of the Vulcan Hammer is like any other melee weapon; its immense size and bulk means that with just one swing the bones of anything it strikes can break, ensuring that a single strike is usually all that is needed to kill any target that isn't heavily armored or hiding behind an immense, three-foot thick wall of titanium steel.  To top it off, the weapon's ends bristle with force shielding, adding to the impact of any strike with extreme intensity.  However, what truly makes these weapons so lethal is their means of assurance that any target will stay dead.
Inside of the Vulcan Hammer is a small, hollow chamber which contains several compact devices that store liquid iron heated at great extremes.  When the weapon is brought to impact with a target, special gaps and smooth edges in the hammer's construction allow for the metal to seep out, engulfing the foe in liquid flame.  This means that those protected by thick enough armor that a glancing blow merely wounds them are soon doused with liquid fire that seeps through any gaps or cracks in the armor and bakes them alive.  While Vulcan Hammers can run out of liquid fire, there is enough inside to be used to fill in enough molds to build an entire standard Oliphant APC with all of its components regardless if they are made of metal or not.  Vulcan Hammers, thanks to their ability to bring death to anything that they strike, have sometimes earned the nickname Hellhammers by those who witness the giant weapons in action.
