ROE change trouble

[Morgan]

Hello all!

I would like to ask for some help. I've been making a campaign and I've got some trouble in one of the missions which i would like to build.

This is the situation: there's a P3 which has to fly above the Straits of Hormuz. I placed a trigger onto the map, which represents the Iranian border in the air. Then the P3 flies into the Iranian air and it gets a message from Bandar Abbas air control that he should leave the area otherwise he will be attacked. I want the Iranian ships (which are placed in the area) and some Iranian F-14s (also placed) to attack the P3 after 70 secs if it doesnt leave the area. It's ok, I've managed to do these things. But I don't know how to do this: when the P3 leaves the Iranian area the Iranians shouldn't attack him/should stop attacking him. I've tried several options but neither of them worked. The ROE never changes back and the Iranians (and Chinese) attack the P3 every time.

Can you, please, give me some help?
