The 2nd Ca Regiment was a division of the 38th Werda Legion. Alongside the 6th Adu Regiment, the Ca Regiment was assigned to defend Leziquk. Ca was the Mando'a word for night. However, when the Separatists attacked, half a legion was not enough. The 36th Legion, which was also a member of the 15th Corps, was hastily deployed to the surface. Even the combined forces could not keep the Separatist Droid Army out, and the entire regiment was among the Republic's heavy losses.
