Just curious, I'm on the fence with this one. Can a scout who used his Den Chief position of leadership to achieve the rank of Star use it again when trying to achieve Life rank? I understand that its a year long position, but can you use the same leadership position twice to rank up? I've always thought of it like service hours. If you use service hours of X, Y, and Z to obtain a rank, then they are used and can't be used again. Any help or advise would be great. Thanks! Dan
