Thanks Marc !
There is, BTW more on Anthropology stirring around in another thread and I anxiously wait and watch your replies

I brought this up because as a young sergeant in a training environment waiting evenings for the aggressors to come (our instructors). I was running a Nike Herc launch platform in the middle of White Sands with two 60K generators connected in parallel (a lot of noise). They had a routine to get us out and about. Pull the fuel lines on the generators and wait.

I would later change the scenario (against my platoon leader's decisions) and move the fuel canisters but connect to fuel lines elsewhere (considered a fire hazard !). I got 'em on the last night

Simple, yes. But in some cases it is rather simple to watch your apponents and learn. Isn't that what they're doing ?
