Can someone give me a practical example on how to use the Anchor Fleet mechanic?
Positioning a chain of ships with resolution 1 active sensors ahead of the fleet, in the direction of incoming missiles. This would keep the missiles on sensors much longer, to rack up the tracking time accuracy bonus.
Positioning ships with smaller, quick firing lasers or rail guns in the direction of incoming missiles. With area fire orders, they might be able to get multiple shots at salvos as they fly past towards the main fleet body. Which lets you do useful anti-missile work with ships that can also do decent anti-ship damage in a beam fight.
It may be trickier to use this than the similar escort mechanic in VB6 though. The AI in VB6 was very fixated on firing at big ships, and would reliably ignore small forward escorts. C# AI doesn't seem to be this way, so may well pick off forward ships if it detects them, so may need to consider enemy sensor resolutions carefully, and even consider cloaking.
