That is true, otoh, you might need to consider moving into a site and go comms dark, not even moving.
That way everyone else has to come to the Avalanche.
Sitting quietly, especially if you're the invader, waiting for the necessary chance to come out.
If you're staying still, even if you lose the initial drive, a Yard Warship loose inside enemy lines, on comms blackout is a major issue. They'll have to scrounge for you, a big fat juicy target that they could use in repairing.
Also case in point, a yardship, great foothold options, especially if you can send messages and coordinate future plans.
