Rulebook states that no ship movement is necessary for PDS to fire when that PDS owner activates system containing enemy ships (in PDS range).
Is the same true for enemy ships owner ? That is: if my opponent activates system (in my PDS range) already containing his/her ships but does not move any new ships into this system , do my PDS-s fire at ships already present in activated system?
The question was asked because of rulebook wording:
The Activation Sequence In Detail section
3. PDS fire
After active player has finished moving his ships into the activated system [...]
Some players treated enemy fleet movement as a requirement for PDS fire.
