Repeating Life Modules drops the Traits and Attributes but doesn't reduce their overall cost. This makes creating senior officers with multiple tours difficult, to say the least. Also, the challenges are different at the Company and Field Grade levels, so I came up with the below. I'll be adding it to the next iteration of my character creation spreadsheet, too.
