|Chronological and political information|
Ace Green was one of the named members of the 15th ATAC Squad, part of the Army of the Southern Cross that was featured in Robotech: The Masters. He was an accelerated graduate of the United Earth Forces Military Academy due to a need to fill the losses in the armed forces. He was quite hostile to Zor Prime, as he held him responsible for the death of his brother, who was previously a member of the 15th Squad and killed in a battle by the Robotech Masters. He himself was killed during an operation on the surface of the Masters' mothership. He was originally in Super Dimension Cavalry Southern Cross, the series which was adapted into the second "saga" of Robotech.
