After the battle between Amestris and the Homonculi ends everyone starts to recover. But there's still a lot of work to be done as a result of all the battles that have been fought. And thanks to Archer's actions, currently the military record files, including but not limited to the ones covering the past investigations and ones covering the past battles, have all been lost. And word has just reached Furor Grunman's ears about a new and currently secret enemy that's going to bring forth a new uprising against the military, to which Grunman doesn't know where to even begin. None the less he's found it best and he's issued an emergency alert out to all the military teams, including Alex Louis Armstrong's team, and also General Roy Mustang's team, to start recruiting new members a bit earlier than normal this year, and gives the order to start their recruiting right away.
