While a player is involved in a space combat in a system, their units in that system are not blockaded, as both players will have ships in the system. Consequently, they may capture their opponent’s units.
- If that player has a unit in another system that their opponent is blockading, they will be unable to capture their opponent’s units.
If, at the end of a combat, one player has no ships, but a space dock in the system, and the other player has only fighters, the space dock will be blockaded before the fighters are removed.
When a ship moves, it does not blockade units in systems it moves through.
