Voltarian 5th/7th "Cotterz' Killers"

The Voltarian 5th/7th is an amalgamated Astra Militarum regiment currently stationed across the entire region of Innsmouth Sector. The bulk of its force comprises the remnants of the Voltarian 5th Infantry Regiment and the Voltarian 7th Armoured Regiment. It derives its nickname "Cotterz' Killers" from its commanding officer, Colonel Thomas von Cotteril.

Origins of the Voltarian 5th/7th
The two regiments that would eventually comprise this amalgamated force were raised from the planet Voltar IV somewhere in mid-M41. The two regiments saw active service across the Ultima Segmentum for almost two centuries before the inertia of travel and bureaucracy brought them both to Innsmouth Sector in 702.M41.

In much the same manner as the legendary Vostroyan Firstborn regiments, the Voltarian regiments also received a steady, dedicated supply of soldiers from their homeworld to replenish their numbers. The origin of this arrangement is lost to the mysteries of time and space, but ancient Departmento Munitorum documents mentioned something called the "Voltarian debt" without any further clarification as to the phrase's meaning. The Departmento nonetheless used this as the basis for their logistical organisation of the Voltarian regiments; it is unknown as to whether this is purely an example of the Munitorum's bureaucratic nature, or if the true nature of the Voltarian debt is still know and simply kept hidden within the sequested archives of the High Lords of Terra. This arrangement came to an end in 721.M41, shortly after the Voltarian 5th & 7th regiments had arrived in Innsmouth Sector. The entire Voltar system was overrun by Chaos warbands, and the entire population of Voltar IV was put to either the sword or the lash.

Facing the prospect of attritional destruction, but initially unwilling to give up their basic concept of Voltarian-only members within their ranks, the commanders of the Voltarians 5th & 7th petitioned Innsmouth Sector's division of the Departmento Munitorum for a merger of their forces. After several months of analysis, the merger was approved, and the two regiments became the amalgamated Voltarian 5th/7th.

As their service continued within the Innsmouth Sector, the Voltarian 5th/7th was eventually forced to drop their long-held ideal of Voltarian-born soldiers being exclusively allowed to their ranks. Facing the reality that the salvation of the Chaos-held Voltar system was a distant hope in late M41, the Voltarian 5th/7th officially began raising reinforcements from Innsmouth Sector's population in 854.M41.
