SORLIE: Wait, if you can only fire the NUSPI once between refuelings...
MURTAUGH: We only get one shot. Hence the importance of precision targeting.
SORLIE: Forget precision. You only get one shot, and you need to destroy an entire army.
MURTAUGH: The NUSPI burns all our fuel at once because that one shot is very energetic.
Hopefully, that one shot will reduce the enemy division enough to give the annie-plant's garrison numerical superiority.
SORLIE: Is it safe to have Sergeant Schlock aboard the same ship as that weapon?
KATHRYN: Not once he hears about what it does, no.
