It's how you do it.
And it's how many people you bring with you to do it.
Usually a bomber, fighter, and gb can stop alot.
As I said, it's all in how you do it.
News flash, LPI don't have bombers. Or Cap ships. We have Liberators. You could probably fly through open space on thruster speed from the Alaska JG carrying Artifacts with a single LPI on your tail the entire way, and still make it to Manhatten alive.
