"Captain, the base power is offline and the lockdown protocol in effect. If we rebuild, the lockdown will end and the doors will open."
Serina

A Lockdown Protocol is a United Nations Space Command protocol that pends to military bases. Should a Firebase receive a certain amount of damage, a lockdown will be enforced, doors closing around its walls and preventing entry or exit. Only when the base has been returned to operational status will the protocol be lifted.[1]
