1. Get to Erbil. There are few airlines that go to Erbil, website will be provided at the end of this post. There is also another airport in Sulaimani. You can buy the visa at these airports.
2. Bring your basic traveling gear and some money for taxi, hotel etc till you are joined up then you will be looked after, $5000 should be enough till you are set up.
3. Don't mention anything to turks about your intentions if you have a stop over in Turkey, best flight route would be directly from EU to Erbil, Kuwait or Jordan.
4. You will be joining as a volunteer which means you probably will not be receiving income from Peshmerga department, thou things could change down the track.
5. Do not share your plans with anyone till you get to Erbil once you get there you can ask police at a station or Asaish (security elements) they will take care of the rest and set you up at a location and most likely you will be joined with other western volunteers. Weapon must be purchased prior to this.
6. It would help if you have some former basic military training or experience.
7. Make sure you only go to Erbil or Sulaimani because the road between Erbil and baghdad no longer exists, and you will only be safe in Kurdistan NOT iraq.
8. Bringing your weapon is not allowed, you can buy your own weapons from a weapon shop/Bazaar which has to be completed prior to going to police station. You can bring own uniform, boots, night goggles and basic military gears...
9. AK47 is $700-$2000 while an M16/M4 is $3000-$4000 but on exit you can sell easily and get your money back.
10. You will be joining as a volunteer thus you can leave anytime you wish.
11. Kurdistan has a 1050km border stretch with the ISIS here are some of the front lines: Gwer, Alqush, Tel Kef, Daquq, Jalawla, Mala Abdula, Zumar, Qere Tepe, Shingal...
