So first of all that first picture is fake and that is not where on the map he was at, that marker is pretty close but not 100% correct.

Second of all there is no clear rules about when you can shoot people close to or in NW airfield, there for was in the middle of making a post in questions/help section. Another thing is that he was in the kos zone if you go by the chat mesage system but he wasnt if you go by the map you can see under the servers tap on the wepsite. The mesage i sent was simple because i thought he wasnt in the kos zone after he complained in chat which i then like 10 minutes later checked if he was or not, he was if you follow the chat mesages that appear when you go in and out of the kos zone. Lastly i would like to mention that there is nowhere in the rules where you can see if you can shot from inside the kos zone to outside of it, and it doesn't say anywhere if you should follow the chat mesages or the map under the servers tab on the website.

You could also have avoided this easily by not standing so close to the zone.

It is common sense. People outside the KOS zone aren't in it, so that means no KOS. As we have two different stories I will just call it an un-clear rule call and leave it at that, but you, Zapzz, have a warning.
