Lookouts, sentries, and guard-duty

[Devonian]

I think this could be a useful discussion but only it was kept more in line with what most peoples genuine circumstances are likely to be, ie: bugging in with their family within their existing homes which are most likely to be in an urban area as most of us will live in Town's, Cities, or villages with neighbours close by on multiple sides.

So the idea of posting Sentry guards 3 houses or 25m down the road (outside of Mrs Jones) and another 2 houses up the road outside Mr McGee's really isn't going to happen. It's great if you have a remote farmhouse or a place on the American plains, but how practical is it likely to be for most of us?

Also how many people will have groups big enough to be able post 2 or more guards on 2 hour shifts throughout the night (and possibly throughout the day) and still have the resources and energy to do everything that needs to be done during the day in terms of collecting water; foraging and hunting; maintenance works; gardening; security etc etc

So to me it has to be more a case of working smart, rather than working hard........
