With first question, do you mean to lock the camera onto a moving object in the ground? mmm Im starting to like the idea
About having anti-radar missions, I will think about that. It might be a risky option, as it might umbalance any mission with SAMs here and there. Actually, anti-radar missions (anti-radar mando missile option) was designed mainly for players and using relatively short range HARMs, not for AI. The reason is the following, if the HARM has longer range than the SAM, the anti-radar AI will kill the SAMs all the time. If the SAM has longer range than the HARM, the SAM will kill the anti-radar AI all the time too, doesnt matter how many countermeasures the anti-radar plane have because he will need to proceed with a direct head-on attack and countermeasures are useless when the plane is always closer to the missile than the countermeasure pack.
If you use long range HARMs, then you might need to use a mando missile center vehicle for the enemy, also controled by a player. In this case the player controling the mando missile center has several friendly AI SAMs under his command, and he may order them to turn on/off their radar at will, so he really have tools to set up an ambush even against anti-radar enemy planes. But AI cannot take this kind of decissions, hence the fact that actually the anti-radar warfare is more a matter for players than AI alone.
