Yes, you can do dat. In fact AI will turn off their radars as soon as they switch to BLUE combat mode (or executing a script to turn its radar off). But it is a bit more tricky that that, I mean, it is not that you want to save that unit turning off its radar, is that what you want is to destroy the anti-radar plane too.
What does that mean in a mission:
- You have a long range radar far away in your territory, over a high hill. This radar is unable to lock on targets, but it is able to detect them (the MMC vehicle).
- Now you know where are your active SAMs, and where are the bandits, so when a bandit is inside the range of one of your SAM units, but it is not heading towards this unit, you may order it to turn its radar on, lock on the bogey and fire a missile, and few seconds later turn its radar off again.
And before you ask, this procedure can be scripted for the AI without the existance of a MMC unit, but the problem is that the enemy is no stupid, more than problably the first planes getting into the long range radar area are not the anti-radar ones, so, what should you (the enemy) do?
