Mobile Suit Gundam MS IGLOO 2: Gravity Front

The Federation forces are routed in face of the onslaught of the Zeon Zakus during the Earth Drop Operations. When the main forces are retreating for resupply, anti-mobile suit tactical squad commander Lt. Ben Barberry 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 previous engagements, is frequently haunted by a spirit called Shinigami, who patrols the battlefield collecting souls of fallen warriors.

Sgt. Rayban Surat is transferred to the 1st Platoon, 301st Tank Squadron of the Federation's 44th Hybrid Regiment as a driver for Lt. Harmon Yandell, a seasoned tank ace. 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, which Snell leads.

Though Operation Odessa is proceeding, the 44th Hybrid Brigade suffers setbacks after its advance is bombarded by artillery fire from Zeon's Dabude-class land battleships. They are reinforced by three RTX-440 Guntanks (advanced versions of the RX-75 Guntank seen in the original series) piloted by a trio of convicts led by Lt. Arleen Nazon, a technical officer blamed and condemned to rot in jail after her lover, Clyde Bettany, defected to Zeon with information on the RTX-440. Arleen vows revenge for destroying her future.
