Parent Formation Triarii Protectors
Formed Ca. 3135-3143[1]


The Twelfth Triarii Protectors were formed up after the eruption of general warfare across the Inner Sphere in the thirty-second century, with the core of the new command being drawn from two distinct sources: mercenaries, who had found themselves stranded on Outreach, and the survivors of the Fourth Triarii Protectors.[1]

After the creation of Fortress Republic the Twelfth continued to hold to the same tenet that the Fourth had held to, the idea that weapons of war could be used as a force for good; the Twelfth continued to use its BattleMechs for peaceful purposes, which attracted the attention of others in the Republic Armed Forces. The Sphere Intelligence Service conducted an analysis of the Twelfth's work and the regions the command had garrisoned, an analysis that was completed in March 3143 and which identified that in many of the regions loyalty to the Republic of the Sphere was higher than the norm. This led the High Command to consider directing other units to adopt the same practise.[1]


In 3145 the commanding officer was Colonel Norishige Shiroyama.[2]
