OK there are plenty of boys who have been there and come back. they stopped here first.
If you do a little reading you will find some of those threads.
There are a great deal of factors involved here.
recommending one light over another is tough with the very little information you have given us.
Do you have any preferences? size battery type. Are you working a deck job or are you going to be in the poop?
do you need a weapon light?
What about night vision?
Do you need to be able to track blood?
What is your budget?
$50.00 or $500.00
It is easy to spend $50.00. Buy a surefire G2L. get a holster appropriate to your style of carry. Do you have a style of carry? Somehow I doubt it . too early. Get a spares carrier. If you can afford it get a Malkoff P60 high output drop in.
OK those are basics.
Maybe you will be working with or inside aircraft. maybe you want a Surefire A2.
I don't know much.
Maybe a E1B or an L1 will do the trick.
You may need to top vehicle inspections. you will need a light which will penetrate the windows and give you good visual on the interior of the vehicle. A light with all hot-spot will serve well there.
OK you have a lot of options.
G2's are good if you are wearing gloves..better maybe than aluminum. Nitrolon is an extremely heavy duty glass impregnated polymer.
Look we don't know anything about what you will need until you tell us.
IMHO Stay away FAR away from inexpensive or cheap Asian flashlights.
Stick with the high quality products from SUREFIRE. They have multiple products designed specifically for YOUR needs. these are battle tested battle approved. MIL SPEC devices.
Yes you pay more. When you life and possibly the life of your buddy depends on it isn't a few bucks more worth it? IMHO you bet your *** it is.
Don't just buy a flashlight. Get a light (or two), get batteries, get a holster which will work for you not just because somebody says it is the best. Get them to back it up. Why is it the best? Do you carry the same way they do?
This is serious business.
Do not make these decisions based upon the opinions of others you don't know. You have 1.5 months. make sure that whatever "system" or flashlight you go with that you spend time TRAINING in it's use under different conditions. Again your life and the lives of those around you may depend on your ability to use a flashlight as a TOOL correctly.
Good luck.
Keep your head down.

Ok, I'm a noob here but I've done my share of browsing. What I need is a "oh-crap-WTF-was-that???!!!" light for when I go to Iraq soon. I'll be walking around in a lot of dark so I want to be able to see anything coming my way from a pretty good distance if I need to. It won't be my primary light as I have other plans for that one. I just need something to keep nearby or maybe on my side in case I need emergency lumens. So far I'm looking at the EYJ, Wolf Eyes Storm, Llamapower Homehunter MRV, T503, and Diablo A9. Right now I'm leaning towards the Llamapower or Tialia but I'd like to do my research a bit more before deciding. Any help would be much appreciated. TIA.
