Thus, the region they needed to defend was actually just half the area. Although this was cosmic space and even defending half the space required caution in every direction, it still reduced the defensive zone by half. Moreover, Lucy Watson understood very well that the enemy might begin with tentative attacks at first.
But after those tentative attacks, a large-scale offensive would soon follow. As long as they could withstand this first assault, the subsequent attacks would be much easier to handle. And if they could engage in a drawn-out battle, that would be good news for them. At least it could distract the Galactic Federation's threat.
