|Unit Profile (as of 2784)|
|Parent Formation||First Army|
The I Corps (also originally referred to as First Corps or the Terran Corps) was a very large military formation that worked for the Star League Defense Force. The Corps' three Divisions consisted of twenty-seven regiments of frontline combat troops (principally BattleMechs, assortment of other vehicles/equipment/infantry) and additional auxiliary support formations.
The Corp's elements were drawn from the Terran Hegemony main military and were congealed into what became the I Corps after participating and training in a massive military exercise known as Unified Triumph Military Exercise in 2571. They and other newly formed League forces were out performed by the Star League's member-states' armies. The troops improved over time and learned better to coordinate between one another by the end of that operation. The First Corps originally consisted of a Royal BattleMech Brigade supported by two Royal armor regiments and an independent Royal BattleMech regiment. The Second and Third Brigade consisted of the most loyal troops drawn from the new Star League's member states.
Tensions between the Periphery Nations and the Star League continued to rise, with tariffs on Periphery goods failing to bring those nations to heel. So the First Lord Ian Cameron and his Star League Council began put into motion unspoken decision for war. Since the massive military exercises on the Periphery border had yielded much needed bases for the League. After Lord Ian would issue his Pollux Proclamation to the Periphery, he would begin move his realm and the Corp in motion. The 1st Corp and its sister Corps were placed at some of these bases which were on the border with the Taurian Concordat's between March of 2575 and December of 2576. The Corp's force would be part of campaign including the III, IV and the VI Corps and backed by an Auxiliary Corps of Federated Suns troops. The Corps and its sister commands would be placed in expeditionary force, commanded by General General Charles Mainstein Wexworth. However, Expedition's assembly was time slow goings. The Federation Suns troops moved ahead of the V's Star League Expedition, and ended up being ambushed in 2577 in the Tentativa system.
In May of 2578, the I Corp and rest of the Expedition would retaliate to the Taurian's preemptive strikes by beginning the invasion. In course of the initial fighting, the Concordat forces lose several key battles to League. However each of these fights the Concordat would send waves of suicidal Concordat infantry Regulars inflicting considerable amount of damage to the League forces. Taurians would slow down the invasion down to years, when it was originally projected as a six month campaign. Among other tactics, stubborn Taurians would employ would be terrorist style attacks, including poisoning water and blowing up SLDF forces in cities by placing bombs in sewers from under them. This would lead to Ian Cameron's announcement of the end of the use of the Ares Conventions by Star League forces in 2579.
The League's Taurian Campaign commander General Wexworth would be killed in battle on in 2582. Replacing him was General Amalthia Kincaid, whom conceives unorthodox plans to counter the Taurian guerrilla forces. However, this was short lived, after two years in command, General Kincaid would be assassinated by Taurian assassins. The Expedition would receive give command to brutal expedition commander of the Outworlds Alliance warfront, General Amos Forlough in summer of 2584. He would have I Corp and the other forces under his command to blockade worlds, and conduct planetary bombardment until these worlds fell finally to the Star League. Casualties began rise during the course of Forlough's tenure, including the seven month battle for New Vandenburg. The Concordat has been reduced by this time to less than half dozen worlds, and Forlough would be replaced by Lord Ian with Lord Damien Onaga. From January of 2590, he would lead the expedition at the head of the elite Star Guards and the war would end by 2596 with the surrender of the Concordat.
After the Reunification War, the First Corps took up station in the Terran Military Region. There they assumed the duties of the Star Guard Corps and became the sole defenders of Terra. The Corps was commanded from a Castle Brian located in Salinas, Kansas. During this time the soldiers of this Corps also served as testers for new equipment weapons manufacturers were hoping to sell to the SLDF. The Corps rotated through the twenty Castles Brian located on Terra as well, testing their readiness.
The First Corps would later be stationed by 2764 in the Star League's Terran Military Region. Stationed in the Terran Hegemony, the Corps and its Regimental and Divisional elements would be among the first be struck down in the first year of the Amaris Coup. Only the 48th and 191st BattleMech Divisions would survive the initial assault of Rim Worlds Republics' assault and betrayal. In the later years of the Star League Civil War, the these two last elements of the I Corps would be destroyed before the conflict would end in 2779.
