Andrew "Andy" Waltfeld (アンドリュー・バルトフェルド ) is one ZAFT's best commanders and pilots. Nicknamed "Desert Tiger", Waltfeld is commander of the ZAFT forces in the PLANT-pledged African Community, headquartered at Banadiya, and is assisted by his executive officer Martin DaCosta. Andy earned his nickname for his great skill at desert combat, as demonstrated on May 30, CE 70, when he defeated a huge Eurasian Federation tank corps at El Alamein, using the new TMF/A-802 BuCUE and older TFA-2 ZuOOT mobile suits. His passions are archeology (especially Egyptology) and paleontology. He lives with his lover, Aisha, who also assists him in his military operations and eventually serves as the co-pilot of his TMF/A-803 LaGOWE. His flagship is the land battleship Lesseps, which is escorted by the land cruisers Petrie and Henry Carter.

During the time that Archangel is traveling through the desert, Andy makes the acquaintance of Kira Yamato, and grows fond of the young pilot, which makes the necessary confrontation between them more difficult. In battle with Kira and Strike, his LaGOWE is destroyed, killing Aisha and badly maiming Andy. Though thought to have been killed, he later re-emerges in PLANT, missing his left eye and arm. Andy claims loyalty to Chairman Patrick Zala and is assigned as captain of the support ship Eternal, but actually joins Lacus Clyne in the Clyne Faction. Aong with DaCosta and most the Eternal's crew, helps Lacus steal the ship, and joins with the Archangel and Kusanagi to form the Three Ships Alliance.

After the Bloody Valentine War, he lives in the Orb Union with Archangel captain Murrue Ramius, who also lost a lover in the war. He receives a prosthetic arm, which conceals a small gun. Later in CE 73, he leaves Orb aboard the Archangel with Kira, Lacus, and Murrue. While Murrue offers him command of the ship, Andy declines, instead serving as a pilot with his custom MVF-M11C Murasame mobile suit.
