During the Battle of Ession, Green Squadron participated in the engagement flying Y-wings.Years later the squadron performed a patrol mission in the Cyax system when it encountered a target which did not broadcast any ID codes. The squadron moved to intercept when the commander of the vessel, Admiral Gial Ackbar, identified it as the flagship Defiance and explained that his ship had received damage to its transponder after encountering an Imperial convoy during a recon mission to the Galactic Core. Green Leader responded to Ackbar's request, and immediately relayed his call to Mon Mothma.
The squadron later participated in the Battle of Calamari and the Battle of Smarck. In the Battle of Coruscant and Battle of Borleias in the Yuuzhan Vong War, it consisted of E-wings and served under Captain Yakown Reth. Squadron members including Reth were reformed into Blackmoon Squadron.
During the Battle of Coruscant, Green Squadron initially covered the Pride of Honor, a New Republic capital ship. However, a senator ordered the squadron to protect his ship instead, resulting in extensive damage to the Pride of Honor. The Pride of Honor was scrapped after the battle due to the damage it sustained.
