With Colorado attacking, and Texas's "unreasonable demands" despite being in no position to make them, the council has authorized the Continental army to occupy the rest of Texas's Arctic Canadian holdings, officially to "maintain stability" in the region to to several other nations targeting their colonies. The Dominion has decided securing an alliance with Colorado is far better than appeasing the Caribbean "barbarians" And so, a swift occupation is completed via Star-Marine landings in key strategic points in the east, followed by Arctic scooter dragoon units moving in from the west(escorted by Drone squadrons). Several "Cookie Legions" are mobilized to secure their old homeland, having been forced out of it after WW7. To curry favor with the surviving cookie population. Being cut off from Texas, which faces a large invasion, and being sparsely populated and just recently gained, any Texan garrisons will be in no position to stop the advance across the barren ice, and are quickly besieged, and offered generous terms of surrender, being that they'll be repatriated to Texas. Those who do not, face orbital strikes and starvation. in the meantime, the Dragoons quickly dig in with light portable fortifications, specifically designed to take advantage of the ice. Light artillery and anti-air/space batteries are towed with the scooters and set up as soon as they dismount in case of Caribbean intervention, not long after they are reinforced with Tripods, Domed fortress seeds, and more tunneling vehicles begin building more permanent underground logistics rails. And after much discussion with her subordinates, Olivia agrees to send a support force to Colorado, securing good relations with them means she can free up troops on the border, and eliminate the threat of feared Coloradian intervention in her civil war and advance on Nest.
