Mastiff and I personally finally tried the Data link. I do not want to start any rant thread.
it will only show.
1. Player's location (if that player are connected)
2. Player's radar locking on target, it will appear on HSD. if Lock is lost, it will disappear
3. It will NOT reveal any of enemy bandits on HSD, again it's only show up on LOCKED target on player that are connected to Data link.
4. ECCM estimate range has been removed.
5. Data link is not same as AWACS, AWACS don't require to have target locked to report the location of bandits. while Data link requires you to LOCK the bandit to make it appear on HSD.
It is similar to Bullseye calling location, what it eliminate, figuring the estimate location of target and calling bullseye over radio comm. except that the Datalink is accurate.
More Observation and Evaluation will be conducted in near future.
