Wolfspear ranks

https://warhammer40k.fandom.com/wiki/Wolfspear#Specialist_Units_&_Formations

Officer Ranks

• High Jarl - The "high jarl" is the title granted by the Wolfspear to their Chapter Master.
  currently High Jarl is Irik Stianolf
• Jarl - A "jarl" is the title used by the Wolfspear for the officer rank the Space Wolves call "Wolf Lord" and Codex Astartes-compliant Chapters refer to as a captain, essentially the commander of an Astartes company-sized formation, though the Wolfspear call their companies "jarldoms."
• Battle Leader - "Battle leader" is the term used by both the Space Wolves and the Wolfspear for a Space Marine Lieutenant, the commander of a demi-company.

Specialist Ranks

• Wolf Priest - Like the Space Wolves, the Wolfspear possess Wolf Priests who combine the roles of Chaplains and Apothecaries found in Codex Astartes-compliant Chapters.
• Rune Priest - A Rune Priest is what the Wolfspear call a Librarian, a title they inherited for Space Marine psykers from their progenitors.
• Iron Priest - An Iron Priest is the term that the Wolfspear use for a Techmarine, much like their Space Wolves progenitors.

Line Ranks

• Pack Leader (Sergeant) - A "pack leader" is the term used by the Wolfspear, like the Space Wolves, for what other Chapters would name a Space Marine sergeant.
• Battle-Brother (Initiate)

Training Ranks

• Neophyte (doesn't really exist in Space Wolves, because the newly received gene-seed are violent and too eager so they put them in Blood Claw pack. Veterans also watch that will pups fall to the curse of the Wulfen.)
• Aspirant

Specialist Units & Formations

• Wolf Guard - Some Wolfspear, having achieved feats of exceptional valour and martial prowess, may become members of the Chapter's version of the Space Wolves' Wolf Guard. These mighty Astartes can lead smaller forces of Wolfspear drawn from other jarldoms (companies), serve as the Wolfspear's version of an honour guard for the most experienced warrior in a deployed Wolfspear force or serve as the pack leader for a jarldom's squads, imparting their knowledge and experience to their younger charges and serving as the equivalent of standard Space Marine sergeants.
• Thunderwolf Cavalry - Thunderwolf Cavalry units are a sub-group of the Wolfspear's Wolf Guard. According to official Imperial records, the Thunderwolf Cavalry doesn't exist and the Space Wolves and their Successor Chapters keep them as a closely guarded secret. Thunderwolves are giant Fenrisian Wolves that stand about the height of a Terran rhinoceros and are used as mounts by the most elite members of the Wolf Guard. Thunderwolves are used in the near-mythical Thunderwolf Cavalry, and are often augmented with adamantium jaws, Imperial bionics, and back-jointed metal limbs that end in razor-sharp blades. The havoc that these creatures are capable of wreaking is said to be startling to even a hardened Veteran Wolfspear. The taming of a Thunderwolf is often used as a ritual trial for a Wolfspear Astartes who wishes to rise into the ranks of the Wolf Guard.
• Wolf Scouts - For some Wolfspear Astartes, the close-knit and boisterous brotherhood of the pack (squad) is not well-suited to their personality, as they yearn for the open spaces and isolation of the Sea of Stars. These Space Marines are selected to become part of a jarldom's Wolf Scout force, providing reconnaissance and disrupting enemy movements. These Space Marines are often already Veterans, as opposed to the raw neophytes commonly used in other Chapters' Scout Marine squads.

Rune Priests and Hounds of Morkai

Amongst the Wolfspear and most other Ultima Founding successors of the Space Wolves, there are a select few who possess tempestuous psychic abilities. Like the Rune Priests of Fenris, these powerful Astartes battle-psykers wield their mental might to aid their brothers and call down ruinous storms upon their foes.

Wolfspear Rune Priests are particularly sinister specimens of their kind. Often wreathed in billowing shadow through which only their ice-blue eyes can be seen, they use their elemental gifts to strike terror and panic into the enemy, plunging the battlefield into eerie darkness before wreaking havoc with flensing blizzards and deadly lightning blasts.

The Wolfspear also make frequent use of the psyker-hunting packs known as "Hounds of Morkai." Marked beneath their Phobos armour with powerful runes of warding, these specialist killers are a formidable threat to enemy Warp-wielders, and their chilling presence has been known to reduce their psychic quarry to whimpering wretches even before their knives and pistols complete the kill.

Chapter Combat Doctrine

The warriors of the Wolfspear are master packhunters, every aspect of their combat doctrine focused on the coordinated tracking, pursuit and destruction of their quarry. The first scent of the foe can be picked up in many ways -- sometimes a single psychic ripple will reach a Wolfspear Rune Priest and give rise to a chase, while other trails may arise by following signs left amidst the rubble of broken cities or the wreckage of ambushed fleets. Whatever the initial trace, the Wolfspear close upon their enemy in complete stealth, observing their behaviour and movements until their weaknesses become clear.

Phobos-armoured Infiltrator packs excel in this role, prowling behind enemy lines to probe defences and quickly silence threats that would slow the main Wolfspear assault. Next, Eliminator packs begin a campaign of terror that relents only when the battle is won, sowing panic and confusion with long-ranged assassinations from the shadows.

With the enemy wrong-footed and bleeding, the full Wolfspear attack begins. Utilising speed and surprise, squadrons of Outriders and swift anti-gravitic transports strike from multiple angles, severing avenues of escape and drawing valuable targets away from the protection of their allies. Thunderwolf Cavalry and other close support packs then encircle their isolated foes and move in for the killing bite, capitalising on the fear their battle-brothers have instilled in the prey.

As much as possible, the Wolfspear translate these same tactics to the void, terrorising and outmanoeuvring larger fleets and launching precision strikes to tear the throats from the most vulnerable targets. Where such clashes can differ markedly from ground operations is the pursuit phase, however, owing to the vastness of space.

Once the Wolfspear have made contact with enemy vessels, they will gladly chase those who attempt to evade them. Whether the trail spans star systems, sectors, or even the nether-realms of the Warp, the Wolfspear regard such pursuits as a test of their stamina and patience, knowing that their targets will eventually tire or succumb to the wounds dealt to them at the battle's outset.

Bled dry and haunted by spectral pursuers they cannot shake off, many targets lose the will to flee, and yield easily when the Wolfspear boarding craft finally make impact.

Chapter Relics

Elemental Shroud - The weave of this Cameleoline Cloak emulates the movements of the elements. As a gust of wind passes, as rain falls across the battlefield, as the haze of heat shimmers the air, the bearer's form flickers in and out of perception. If the bearer remains stationary, they are clouded entirely, a ghost lost to the wilds.

Totem of Storms - This runic totem empowers the Rune Priest who bears it. As they channel their psychic energy, the totem awakens, gathering a tempest overhead. Its presence is a reservoir of psychic energy the psyker draws from, giving them mastery of psychic powers manifested in the battle.

Blacktooth - Blacktooth is a power sword kept under the watchful eye of the Chapter's Rune Priests, for it is whispered that dark spirits empower its edge. It is bestowed only to warriors who hunt alone, for the bind between blade and bearer takes a toll on the bonds of brotherhood. When the bearer is seemingly lost to the hunt, the Rune Priests reclaim Blacktooth and return it to the Chapter's vaults as the bearer is brought back into the fold.

Notable Vessels

each of the Chapter's seven jarls -- the alpha warriors largely comparable to Wolf Lords or Primaris Captains -- operates from a personal strike cruiser, accompanied by a fleet of smaller escorts and attack craft.

1. Umbral Claw (Strike Cruiser) - The Umbral Claw is the closest the Wolfspear come to possessing a flagship or a mobile fortress-monastery, a tradition generally eschewed by the Wolfspear who prefer that their fleets remain highly maneuverable. This vessel bears High Jarl Irik Stianolf himself through the void, acting at once as an armoury, spiritual sanctum and the lordly court of his jarldom.
2. Strike Cruiser of Jarl Halga Hyrdred
3. Strike Cruiser
4. Strike Cruiser
5. Strike Cruiser
6. Strike Cruiser
7. Strike Cruiser

Strike cruisers are capable of carrying one full company of 100 Space Marines as well as all of their needed armoured support vehicles. 

While several of these forces will gladly work in concert to harry and bring down high value targets, each Wolfspear jarl's flotilla is fully autonomous, capable of hunting alone for standard years if need be. This has inevitably led to subtle variations of culture and fighting style between the different roaming fleets of the Wolfspear, and on the rare occasions when the Chapter convenes in full, the warriors of each jarldom gather to exchange hunting tales and scrutinise the deeds of their peers.

Nonetheless, prolonged campaigning puts logistical strains on even the most resourceful commanders, and like other roaming Adeptus Astartes Chapters the Wolfspear have established clandestine outposts in a number of key strategic star systems.
