Due to the delicateness of the rescue mission, the commanding General in charge of the First Marine Division at Camp Pendleton calls for volunteers only. When they find out who they will be attempting to rescue they all volunteer to go even with the strange circumstances they would be facing--- territorial problems and having no weapons with them when they leave.
