Question here for the peanut gallery: Does the difference between insurgents in Rhodesia and those in Afghanistan depend on scale? Are we picking the right battles?

A typical Rhodesian TTP, from what I have seen, involved massing for raids against White settlements. Questions:

1.) How often were the insurgents detected and acted upon?
2.) What was the terrain like around these settlements? How close were they to villages?
3.) How does the "body count" compare to Taliban raids against, say, COP Keating and Wanat?
