In a military situation, IR will reveal you if you are being looked for. Walking around at night or a fire - you be found.
I plan to bug in. If I have to, I can cache items that may be "contraband" near the house. Close enough to get to, not close enough that they can link them to me. And pretty much, unless someone is really looking closely, the stuff won't be found.
And if the Zombie Applesauce happens, I'll be on the roof with a scoped .22 and a tally sheet.
