During the Battle of Coruscant they assisted Omega Squad and ARC Trooper Lieutenant Aven in defending the HoloNet News and Entertainment Headquarters building from Separatist attack. They succeeded in protecting the building from droid attacks. They then assisted the Coruscant Security Force in maintaining domestic security on the capital. After Order 66 was enacted and Palpatine established the Galactic Empire, Yayax Squad deserted and joined Kal Skirata on Mandalore. They were taken to Mandalore by Nyreen "Ny" Vollen and A'den Skirata when she brought the body of Etain Tur-Mukan to Kal. The squad, alongside former clone commander Levet, became carpenters and farmers.
