Since you were in the military, let me ask you this. For the purposes of this question your rank is SGT. OK. You and another SGT (both the exact same rank and both men) are given a project to accomplish. The project has various tasks to complete. Your CO did not specify who does what, just get the job done. How do you and the other SGT decide who does what to get the job done?
By date of rank ?
Sorry...not trying to be a pest.
