Hell is a Cold Place
Aside from a few remaining Castles Brian, active combat operations in the European, African, Asian, and Australian continents had ceased by January of 2778. The 17th Army's operations in the Caucasus region continued into that January, but the heavy lifting was done by the XLVIII Corps, though with heavy losses, including 80% of the 38th Jump Infantry Division's strength.
The 741st is assigned to guard the Odessan ports and shipyards while it recovers its strength. Delta Company is declared a total loss, leaving Echo, Golf, Hotel, and India companies as the only fully combat-capable units in the regiment. During this time, much of your duties include guarding a particular ship manufacturer's yard. After his rescue, Dr. Higgins disappeared for a month up the chain of command. He returned in May of 2777, accompanied by a large number of Intelligence personnel and engineers, and disappeared into the shipyard. You see him only occasionally, while on patrol. He takes lunch with WO Banzai, a few times, but flatly refuses to tell what's inside the yards which is so important.
In July of 2778, you find out.
Preparations for the invasion of the Americas has begun. Dr. Higgins has been hard at work for a year, building prototypes and manufacturing specifications for a series of BattleMech delivery craft (which some wag named "Higgins Boats", over his strenuous objections) intended for use in an amphibious assault against the American coastline. In a way, it make an insane sort of sense. The SDS systems overwatching the Western Hemisphere are the best in known space, both in quantity and quality. It is rumored that it is accurate enough for naval-grade PPCs to track, engage, and destroy conventional fighters with regularity...to say nothing of a Mech-carrying DropShip. This claim that is never officially dispelled.
For the remainder of 2778, shipyards across Asia and Europe churn out these "Higgins Boats", with their massively-armed flat bows which double as assault ramps. The armor is so thick that the carried Mechs actually act as ballast to keep the craft from tilting forward. The craft are overbuilt, each able to carry a full company of 12 BattleMechs, plus an additional 2 Mechs or armored vehicles for specific battlefield roles.
In December, you learn your target. Operation ANCHORHEAD will be an assault against the Anchorage beaches by the 9th Jump Infantry and the 322nd BattleMech Division. Each Regiment of the Antarctic Division will carry two companies pulled from 17th Army Independent Regiments to act as a mobile reserve and "ready-response" force. With your pedigree, you're assured of the premium spot: ready reserve with the 1138th BattleMech Regiment (Lucas's Liberators). They will be the first to hit the beach.
The landing is scheduled for 7 January, 2779, but poor weather and stiff seas delay the action. SLDF scouts, having infiltrated their way into position weeks earlier, report that the weather is scheduled to break soon. So it is that, on the afternoon of January 14 January, 2779, you set sail across the Bering Strait. You are scheduled to hit the beach at 0330, 15 January.
Godspeed.
