During training:
Lt. Col. Moore: All right, your officer's dead, what do you do?
Platoon Sergeant: First—
Lt. Col. Moore: All right, he hesitated, HE'S dead! What do you do?

"It was once rare for a Galaxy-class to be commanded by one as young as me but the wars with the Klingons and the Borg have a way of eliminating the complacent or unlucky and clearing the way for new blood. Hell, that’s the reason I got my first command, after the Borg killed or assimilated the entire command staff of the Kagoshima, which left me, the second shift weapons officer and the senior-most JG afloat, the ship’s acting captain."
Captain Kanril Eleya, Bait and Switch

Bir: “Code Dragonfly means we’re cut off, ma’am. The portal home just slammed shut hard and fast enough to cut a Black Knight in half, I can’t raise Avalon on our comms, and whatever that little wave was, it just cut all of us from mental and spiritual contact with Avalon as well.

We’re cut off, and I have no clue how long that will last. [...] And in accordance with His Majesty’s last instructions from His own lips, you are in command until relieved, Lieutenant. Orders, ma’am?”
Asuka (shocked): “Scheiße!”

General der Artillerie Helmuth Weidling: What's going on? Why am I to be shot?

General der Infanterie Wilhelm Burgdorf: Go on.
General der Artillerie Helmuth Weidling: [emphasizes his Iron Cross] You see this, don't you? Don't use that tone with me! Now do what you have to!
General der Infanterie Wilhelm Burgdorf: I think you should explain it to the Führer yourself. Come along.
[later]
Generalfeldmarschall Wilhelm Keitel: Congratulations, your report impressed the Führer. He has appointed you in command of Berlin's defenses.
General der Artillerie Helmuth Weidling: ...I'd rather have been shot than have this honor.
