The idea is simply to measure the ratio of sales to everyone else. You don’t need to make judgement calls about which non-QBSR employees “support” sales.

That’s an important distinction from the military usage. Here, the “tooth” is the total headcount of your company’s QBSRs, while the “tail” is simply the entire remaining headcount of the company.

A bottom-up approach multiplies quota bearing sales reps (QBSRs) by their quotas to arrive at a projection. There are any number of methods sales leaders can use to link sales targets with the size of the sales force.
