Mobile Suit Gundam MS IGLOO The Gravity Front

(U.C. 0079.04.26 - 0079.04.27) The Federation forces are routed in face of the onslaught of the Zeon Zakus during Earth Drop Operations. When the main forces are retreating for resupply, Lt. Ben Barberry, who leads an anti-mobile suit special tactical squad utilizing the "Regina" missile launcher, is ordered by his arrogant superior, Col. Michael Colmatta, to advance and ambush the pursuing Zeon forces. Unknown to others, Barberry, who loses every subordinate in the previous engagements, is frequently haunted by a spirit called Shinigami, who patrols the battlefield collecting souls of fallen warriors. Barberry and his platoon arrives at the outskirt of a ruined mining town and receives information of two Zakus (instead of three from the intelligence report) rampaging through a nearby supply depot. The ambush is set but failed to achieve an immediate kill when one of the squads opens fire prematurely.

(U.C. 0079.07.21 - 0079.07.26) Sgt. Rayban Surat is transferred to the 1st Platoon, 301st Tank Squadron of the Federation's 44th Hybrid Regiment to become the driver for Lt. Harmon Yandell, a seasoned ace of the variant-5 Type 61 tank. However, Yandell is a man with his own demon — he survived an encounter with Zeon's feared "White Ogre" Cpt. Elmer Snell at the cost of his left leg, and sees himself as a homeless dead man walking. His previous drivers have either been killed, or gone insane seeing the Death Deity haunting Yandell's back. After seeing Yandell's irrational behavior, Surat asked his commanding superior, Col. Colmatta, to relieve Yandell's command. Instead of doing so, Colmatta approved Yandell's mad plan to launch a night assault on the oncoming Zeon force, led by no other but "White Ogre". Yandell's tank squadron ambushed Snell's Zaku tri-squad at a plain where the Federation suffered a major defeat the previous day.

(U.C. 0079.11.08 - 0079.11.09) Though Operation Odessa is proceeding, the 44th Hybrid Brigade suffers setback after its advance is bombarded by artillery from Zeon's Dobday-class land battleships. They are reinforced by three Guntanks piloted by a trio of convicts led by Lt. Arleen Nazon, a technical officer blamed and condemned to rot in jail after her lover defected to Zeon with information of the RTX-440 project. Bearing deep hatred to the man who betrayed her, Clyde Bettany, Arleen vows revenge for destroying her future. The offensive resumes on the second day and the Federation forces again suffering casualty from the well dug Zeon defence. Arleen's team penetrates enemy lines to provide artillery reconnaissance, before storming and breaking into the Zeon forward base. In the mist of battle, Arleen's two teammates self-detonate their Guntanks, taking out one Dobday.
