Sagitarii Power-Spear

Larger and packing more power in comparison to it's smaller Mechanicum cousin, the Gotrenag, the XXth Legion worked alongside the Adepts of Mars within their ally fleets, wanting to make a version for themselves that would prove even more deadly. In particular the grind of the First Rangdan Xenocide showed the Legion the merit of the weapon type, able to punch through metre-thick armour plates with ease to would the enemy within, or set them up for a follow-up attack.

Design
As well as being physically larger to accommodate the size of the superhuman troops, the extra space allows for a more comprehensive internal power system, able to handle the activation of the EM rails at any time. The secondary benefit comes along with the privilege of being a Space Marine itself. The access to resources the Astartes Legions have far outstrips most within the Imperium, this means that the Adamantium rods that make up the main lethal element of the weapon are easily replaced. To take advantage of this access to resources the Sagitarii variant has a set of locking lugs that can lock onto and let go of, the adamantium rod. This allows the rods to be used normally with the lugs locked on, or to use the system as a launcher to fire the rods out using the electromagnetic rails at high speeds.

Although limited in it's armour piercing potential due to the scale of the electromagnet rails, the rods have proved capable of penetrating light vehicle armour from up to 45 metres away, and easily able to penetrate most forms of infantry armour. While still a single-target weapon, this functionality gives the marines the ability to engage with one enemy and kill or disabled him within the effective range, and either reload another rod or switch to using it as a melee weapon for any subsequent enemies.
