What this part means

The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.

Its job in the formula

A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula

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…
