Based on a discussion between Monbvol, Cray, and me, we thought it would be useful to widen discussion of the issue of base pay and Rank as outlined in Campaign Operations (pages 24-25).
The problem, as I see it, is that the chart in Campaign Operations, and all the supporting examples, use the base pay without modifiers for Rank with the sole exception of "Officer". That seems to imply that the majority of personnel in a unit are Rank "0", whatever that means.
As written, the current formula for pay basically means a Rank 1 trooper would receive 750 (the base pay for an infantry trooper) x 1.33 (which is Rank/3 + 1), or 1,000 C-Bills per month. Again, all of the examples presented in the book don't do this. The formula also lacks guidance on rounding, but any rounding at all would impose unreasonable steps in the pay system (i.e., Rank 2, 3, and 4 personnel would all receive double the pay of a Rank 1 trooper, with no differentiation between them).
My initial proposal is to align Rank 1 pay with the base pay by imposing a -1 to the Rank trait in the formula. This is only a first approximation, but it could work.
