Dude,
Use your authority or just the fact that you have a gun to get into a nice spot for some shots. Most people will never be able to get there and do that
any hills that overlook a city or small village, and interesting things that are off limits to normal civilians, go there and shoot , what an opportunity.
If you find any underground bunkers or caves, go through and get some good shots, years later make a book.. who knows.
Your lucky , a gun AND a camera.
About the meter, personally dont think you need it, if your shooting digital you can get instant feedback from your lcd and youll learn real fast which big mistakes to avoid. Also most of the stuff your capturing will be a mile or more in the distance, so impossible anyways to properly use the meter.
the polarizer will help you pop clouds out nice, and anytime you get near water, or car windows, helps take away a LOT of the reflection.
the ND is also great, just a little more setup time, but its still nice.
i would keep the tripod with you in case you want to shoot at dusk with the polarizer. if your shooting landscapes always use the release cable so you dont wobble your tripod . dont press the button on the camera to shoot unless your shutter speed is like 1000 or more.
Keep in mind you can setup the tripod at night where there is a litle ambient light in the distance from a city or something and do a 3-5 minute exposure shot and thats something that ive never seen a long exposure night shot from over there ? doubt anyones done that, ....
cheers..
