In C.E. 73, the Phantom Pain ship Girty Lue used four Dagger Ls to attack the ZAFT military colony Armory One, while its three Extendeds stole three new Second Stage Series Gundams. The Doppelhorn Dagger Ls attacked a Nazca-class outside the colony, while the Dark Dagger Ls used a Mk39 Low-recoil Cannon each to destroy a Laurasia-class inside the space dock and eventually the dock itself. Two of these suits were later destroyed by Minerva pilot Rey Za Burrel in his ZGMF-1001/M Blaze ZAKU Phantom during the Skirmish in the Debris Belt. After the "Break The World" Incident carried out by rogue ZAFT soldiers, the Alliance sent a fleet to take down the PLANTs with a large mobile suit force consisting of Dagger Ls and the new GAT-04 Windams, going into battle against ZAFT's mobile suit forces. Around the same time, a group of Dagger Ls, including one equipped with the Launcher Striker, and a Windam attacked the Junk Guild as the group was alleged to have launched an attack on an Earth Alliance base, but they were defeated with help from Kaite Madigan's ZGMF-X12A Testament Gundam and Jess Rabble's ZGMF-X12D Gundam Astray Out Frame D.
