- enhanced AI's hearing abilitys significantly

This update is gonna make some people whine, and make some people love the mod more.

AI will now hear gun shots up to 800m away (was only 100m before??) This will expose the unit hidden in FOW for a certain (short) time period, per gun shot. This will also allow your units to engage at units hidden in fow if they open fire first, which will allow your units to open fire back at the enemy. So no more hidden units firing at you. If they shoot, they will be exposed. AI will know where they are (by "hearing" the gunshots) even if they are not in targeting range, and will start planning a way to get in range, and attack the "heard" units instead of going for the flag. This changes the AI's behavior significantly.

Everything else in the mod is almost scaled to real life values, so why not do the same to hearing? Imo, the new hearing really brings out the best of the ranges for both vehicles, and infantry.

And before you whine about being spotted to far away now, use your noggin. Dont fire your weapons until your units are in a good position to take on the fight. Once you open fire, all hell is gonna break loose and you will expose your position to whatever the enemy might have. So just be ready.

This update also seems to fix the lazy AI engagements up close. Having the extra hearing really makes the AI think more. So yes, the AI just got a lot harder/smarter.

Nevertheless, I wanna hear some feedback on what you guys think, thank you.
