I think being playing this correctly for some time. However, last night playing with some people who never played with before the way they used Locks was different to my use.
My reading of the rules for target locks: -
1 - Aquire lock as an Action
2 - Fire at a locked ship using a charge token
3 - Use the target lock if I want to re-roll the attack dice
4 - End Phase target lock stays on the targeted ship
Or am I missing something in the rules or FAQ ???
