Oklahoma is a state inside the United States of America.
Not a lot is known about Oklahoma during the outbreak. It can be assumed that it followed the example of California, with state and local police being among the first responders, with these first responders being joined by military units when a state of emergency was declared, and in accordance with the Federal Government's plans.
By the finale of Season 6, a nuke was launched by the Doomsday Cult in the nearby state of Texas, devastating the entire area. However, it is heavily implied that Oklahoma was not devastated by the blast due to the warheads mostly hitting southern Texas and eastern Louisiana.
