CGS arc

The CGS arc is the first story arc in the Mobile Suit Gundam: Iron-Blooded Orphans series.

This arc revolves around both Gjallarhorn's attempts on Kudelia Aina Bernstein's life, and the rebellion that was staged within CGS.

Assault on the CGS
Kudelia Aina Bernstein hires Chyrse Guard Security to escort herself and her assistant, Fumitan Admoss to Earth. Kudelia hopes to negotiate with the Abrau bloc Prime Minister in favor of the Mars Independence Movement. Kudelia's father, Norman Bernstein, is opposed to the social movement and sells out his own daughter to Gjallarhorn. Gjallarhorn's Mars Branch Cheif, Major Coral, makes a deal with Nobliss Gordon to recieve funding for the branch if Kudelia is killed before leaving Mars. Major Coral orders Lieutenants Ein Dalton, Crank Zent and Orlis Stenja to attack Chryse Guard Security and assassinate Kudelia.

Chryse Guard Security are made up of hired soldiers, many of them being orphaned children. Kudelia views this misfortune as a direct result of the Earth Sphere's oppresive rule on Mars. She requests that the oprhans be the ones to escort her to Earth so that she can further understand the people the Freedom Movement are standing for.

As the Mars Branch of Gjallarhorn has become increasingly independent and corrupted in recent years, representatives from Gjallarhorn's inspection divison travel to Mars. They are Gaelio Bauduin and McGillis Fareed, two members of Gjallarhorn's most respected familities. Before they arrive, the Mars Branch commences their attack on the CGS in secret.

The two sides begin battling by engaging in Mobile Worker Combat. CGS's Third Group, led by Orga Itsuka are tasked with distracting Gjallarhorn's forces while the other members set up an ambush. Orga quickly discoveres that the CGS is actually planning to use Third Group as a distraction so the adults can escape unharmed. Orga initiates a plan of his own so that he and the other orphans can survive the battle.

He has Biscuit Griffon rig the First Corps Mobile Workers to set off flares, giving away their position during their escape attempt. This relieves most of the pressure off Third Group until Gjallhorn's lieutenants arrive with Mobile Suits.
