i added bits. e.g clarifyings its not SI values used
Tactical Retreat
When attacked by a superior opponent the own fleet can flee from fight in certain cases:
Off/From a 5:1 power ratio of the ships in fight a fleet can retreat. Thereby the Units of the attacking ships are compared to the units of the defender. (these units are not SI, just value. i.e a battleship is 45k metal 15k crystal = 60k)
Admiral users can set a lower power ratio (3:1) at which the own fleet can retreat from battle. It can be set in the fleet menu at "Tactical retreat".
Defensive structures will not be taken into account for the calculation of the units, civil ships only count for 25% (rounded).
Units of fleet at ACS attack or ACS defend are added up. (currently all acs attacks are dishonourable pretty much also. note that)
Tactical retreat runs automatically in the moment of fight and needs 1,5 times as much deuterium as the fleet would need for a flight to the neighbouring position (Attention: Deuterium must be available).
After retreat the fleet is instantly available again.
Deathstars, Espionage Probes, Solar Satellites and fleets at ACS defend can not retreat.
For moonshots and similar things, tactical retreat can be deactivated in the fleet menu.
There are also some cases in which tactical retreat does not take place:
Tactical retreat is linked with noob protection and ends at 500.000 points (in old universes 50.000 points).
Fleets from inactive player don't escapes.
In honourable fights the fleet can not retreat (see below for honourable fights).
Fleets can only retreat completely. If there is a lack of deuterium, no ship can retreat.
Additional notes:
In the current version 3.0 the option for setting retreat behaviour is available even if the player is not in noob protection anymore and tactical retreat is not possible. Please don't get irritated by that.
As attacking player the option "Return upon retreat by defenders" can be activated in fleet menu III. If the fleet of the defender retreats, your own fleet also retreats and no fight takes place.
as for bandits fleeing yes,
THe only negative thing about being a bandit at the moment is you have 100% res raided from you.
for top 100 military powers its not really an issue. instead of having 75% raided you have 100% raided, so its not much difference...
