R=NcombatNtotal−NcombatR = \frac{N_{\mathrm{combat}}}{N_{\mathrm{total}} - N_{\mathrm{combat}}}

Why this formula appears here

The measurement problem is definitional, not statistical. Write the ratio as R=NcombatNtotal−NcombatR = \frac{N_{\mathrm{combat}}}{N_{\mathrm{total}} - N_{\mathrm{combat}}}. and every term is a boundary dispute. Does the denominator include contractors, and if so only those deployed forward or also those in depots at home? Does it include host-nation labour, coalition-provided support, base life support, medical evacuation, theatre engineering, or the transport crews of another service moving the force into theatre? Does an artillery unit that never leaves a fire base count as tooth? Does a signals detachment embedded in a manoeuvre battalion? Because these choices are made differently by different authors and rarely stated at the same level of detail, two published…

NcombatN_{\mathrm{combat}}

Symbol N_combat

NcN_combat is one of the signed contributions combined to compute the quantity on the left.

NtotalN_{\mathrm{total}}

Symbol N_total

NtN_total occurs below the fraction bar. The quantity above the bar is divided by this expression; zero is excluded as a denominator.
