You can put the missiles any way you like really. Some units like sidewinders first others like AIM-120s. Pilots like to have the missile they use first on the outboard stations. On the ALE-50. Id use it. On a Wild Weasle mission they would want that there. Its a towed decoy that goes behind the aircraft. If its hunting SAMs you would want every option you have with you in case they get a couple up.
