In your hypothetical patrol, how long is it both distance and time? How far away from the PB. How big/what readiness is the QRF in case the patrol gets in a contact. How friendly are the LNs? How densely populated is the area. What’s the temperature?
Do you mean what are the contingency plans to bring in logistics beyond immediate combat requirements?
Or is it easier to have the blokes chin strapped carrying the contingency to save you the bother?
