With this information, we were able to calculate the percentage of positions in each
grade that would need to be filled by full-time cadre personnel during peacetime for each of
the cadre forces examined in this dissertation. To do this, we divided the total number of
Army IRR personnel available for BCTs in each grade by the number of cadre personnel
needed in each of the cadre forces. These results are shown in Chapter Two of this paper.
We then used this data to calculate the cost of a peacetime cadre unit relying on IRR
activation using the methodology described in Appendix B.
C.3—CALCULATING COMBINED STRUCTURE
The final cadre structure analyzed in Chapter Two designed a cadre unit that would
depend on both a wartime increase in promotions and activation of the IRR. We calculated
this structure by first adding the percentage of positions in each grade filled by promoted
officers/NCOs to the percentage filled by IRR officers and NCOs for each of the cadre
forces. Then, we subtracted this fraction from one to determine the number of officers and
NCOs in each grade that must be retained in peacetime. We calculated the relative cost of
