It really does depend on the scenario that you are thinking of. For my info, lets say its a red dawn type event where a foreign military has
Bug out bag
your bug out bag should be somewhere close at all times. Namely your vehicle secured some way. Your vehicle is usually always
near you, at school, work, shopping etc. If you have to take up time to make your way home, then you are already behind the power curve.
Being in a town or city is a bad idea. Those will be the first to fall as large concentrations of people and strategic places will be the
first targets. The sooner you leave the better. The initial response will be shock by the majority of the population along with disbelief. Within 45
minutes to 2 hours people will realize the gravity of the matter they will be wanting to leave or panic. The sooner you leave, the better situation
you will be in.
Avoid major roads and highways. Once again this will be the major concentration of people that will be a first target. They will
be the first to close off, or will be clogged with people trying to escape. Sticke to back roads. On technique is to use a quad, or atv type vehicle
to take railways out. Atv's are narrow enough to fit between the rails, and they will not be clogged. Just watch for trains
and it will be a
bumpy ride. Make sure you know which way is out of town. Do not try to drive on rails with your car/ truck, there is a very high risk of losing
control and rolling over, screwing you in the end. Avoid large industrial complexes/ stadium like areas. They are more then likely taken being used
as a staging refit area. They also house high vantage points for them to defend against assaults.
Sewers are a really bad idea, they contain toxic gasses, and most are not as easy to navigate as one thinks and make a effective chock
point. Add that trying to open a man hole cover from underneath is nearly impossible. Sewers are easy to secure for the military. Spread some powder
CS and when someone walks thru they are blinded and disoriented by the tear gas. Your only protection would be a gas mask, but then the military can
throw High concentration smoke, even with a gas mask you would be suffocated.
Can't leave home
If you are stuck at home for whatever reason, you are in bad shape. Secure your doors and windows by any means possible.
Try to make your house look not occupied. Make a lookout point at the highest point of your house. If needed cut holes in your roof with just enough
room where you can scan 360 degrees. Make sure you place some type of roof colored tarp like device over the holes to prevent rain from entering or
from being obvious that you have look out peep holes. Be prepared to defend your house. Make an unoccupied house several houses down look to be a
better target. Start a fire in the fire place, throw trash out front etc. That would draw the attention of a force and will possibly give you enough
time to escape while a force is focused on that house. Pay attention to if they are doing a methodical house to house search. Units use specific
signs or methods of marking searched houses. Try to copy it and mark your own house as a last resort if you have no other means. It might just make
a unit bypass your house as most platoons cannot talk directly to each other.
Most military units thermals see a 1 degree difference in temp. They cannot see thru walls and sometimes windows block the
sights (depends on if thermal energy is being reflected or not). They can see thru (to some degree) fabric like tents or curtains. Also if its
winter and you are hiding inside with a house with a heat source the walls and roof will become hot in the thermals giving you away. Also if you are
in the woods, no mater how deep, if you have a fire or running vehicle the heat will warm up the leaves above as it rises, and be a big arrow pointing
to your position. You are just a mortar round away from meeting your maker. One way to lessen the effect is to start a fire deep into the side of a
mound of dirt. The dirt will absorb more of the heat making it less noticable (but still dangerous)
Hope this helps some, sorry its a book. Feel free to dispute my thoughts
