Looking for some German Phrases

[ffutures]

I could try Alta Vista, but I suspect that some of the readers here will be able to give me better translations:

Signs:

"Military Contracts Office."

"Civil Identification Bureau."

"No admission to unauthorised personnel."

"Important notice: all personnel without exception must report to the security desk on arrival on Tuesday morning."

"Intruders will be shot."

"Maintenance Department."

Speech:

"Halt or I fire."

"Resistance is futile."

"Surrender!"

All help very gratefully received.

Forgot to ask: what would the most literal English translations of these words be?
