From Quake II, PC version, the yellow laser control computer in the Detention Center is guarded by a Gladiator. On the balcony across the courtyard is a Guard. It's not hard to get them fighting each other, which saves ammunition and provides a little entertainment. Finish off the winner (the Gladiator) and press in the keyboard of the computer.
