In the same vein, all of the wingman trouble/death lines hold a special place in my heart.

INCOMING!

"I have no intention of escaping, Colossus, nor will I surrender. Even if I send my crew to hell with you, this monstrosity will be destroyed!" -Admiral Koth

"Sevrin, you're late! Vasudans blasted my entire squad and two cruisers out here! You want a rendezvous? Scan that debris field! That's the Sunder right there! You're a disgrace to the NTF, Sevrin! I'm filing a report!"
 
"The C.O. of the Sevrin has taken the brunt of Bosch's wrath for the Sunder's alleged destruction. The captain and his lieutenants have faced a summary court martial and will be executed at 0700. When you sign up for the wrong outfit, you get what you deserve." - Lt Cmdr Snipes

"Capella has gone supernova! Repeat! Capella has gone supernova! You must get to the Vega node and engage your jump drive now!"

"This is Allied Command, signing off. Godspeed, pilots." - GTVA Command

"As humanity emerged from its Neolithic infancy, they believed their voyage across the sea of stars woke a dragon that slipped beneath the waves, that the Shivans were birthed from the flux of subspace, and their destruction was the revenge of an angry cosmos."  -Admiral Bosch

I can live with being a pawn if the game makes sense.
I can live with being a prawn if the cat food makes sense.
I can live with being a pawn (on a board of bone) if I have contingencies for the contingencies.

yo dawg we heard you like contingencies so we made contingencies for your contingencies so that when your contingencies fail you still have a contingencies

"Send fighters! I... I know they're following me, send everything you have now!"

Here we go again...

First off, from the official campaigns...

Wingman: Dammit, Actium, watch that friendly fire!
Command: Avoid the beam and you won't get hit, pilot!

Snipes: That was a little too close ... we gotta wait fifteen minutes to change our shorts. Well we've ... heh, STOP LAUGHING THERE CO-PILOT.

Snipes: Do not engage, I repeat ... ... ... ... dom dom dom dom-dom dom dom dom. Okay, had your fun?

...and now, from the fan-made ones...

We destroy to preserve.

Your people are safe now, Wanderer. Go now, and bring the rest of your race to enlightenment.
We will meet again when your people are ready.

Alpha 1: AAAAHHH!! I'M BLIND!
Command: You know I was sure we installed sunshields on all ships by now...

GTD Sasquatch: A Rakka...A Raskcha...RA...some Shivan cruiser just came out of the portal. Go kill it!

GTD Sasquatch: Ka-BOOOOOOOOM!!!!
Wingman: Uh, sir we can hear the explosion.
GTD Sasquatch: No you can't, there's no air in space. Sound can't travel through a vacuum!

GTD Sasquatch: You know, I think it would help if I started firing the beam cannons...

GTD Sasquatch: NOOOOOOO!!! How COULD YOU?!? BASTARDS! FEEL THY WRATH!
Wingman: Uh, it was only Beta 2, sir.
GTD Sasquatch: What are you talking about? They cancelled Firefly... again!

Alpha 1: AGH! Son of a...
GTD Bastion-A: Whoa, a ship just came through the Stargate! Looks friendly enough. Can we close the iris yet?
gtd harbringer: I keep telling you, that's not a Stargate, and stop making references to it before we get sued.
GTD Bastion-A: This wouldn't be happening if we had a DHD!
gtd harbringer: Just shut up and kill Shivans. You there, 4lpha 1 Clone, help kill Shivans too!

gtd harbringer: The Bastion-A has been destroyed! FINALLY! Where's your ship-guardian NOW? Er, stand clear of the explosion!

gtd harbringer: Great, another Sathanas. Command, we're gonna need bigger ships.
Command: Right, ok. How about the Icanus? Or maybe the Gargant?
gtd harbringer: This isn't a modded campaign! Just send the Colossus Reborn.
Command: You know if we had done this in Inferno like I suggested...
gtd harbringer: Just deploy the Giant Watergun and be done with it!

This is the GTVA Co...

HOLY CRAP! FULL STOP!! FULL ST...

NTF Iceni 2: Welcome my friends... TO THE DISCO INFERNO ASTEROID BELT!
Alpha 2: Dear god my ears! AAAAHH!!
Alpha 3: There goes Alpha 3...

Alpha 1: AUGH! WHAT THE F...
GTD Sasquatch: You're back! I knew it!
GTCv Firebird: Then why were you betting against him?
Alpha 1: Who cares right now. We got very angry people coming through that portal in a few seconds. Killing them would be nice.
GTD Sasquatch: Couldn't we just talk it over like adults? This war thing is getting pretty old.
Alpha 1: Uh... They're the ones that cancelled Firefly...
GTD Sasquatch: ...READY THE MESON BOMB!

GTCv Firebird: We shall return as Firefox!

NTF Roffle, may the god of Plasma Core Insertions have mercy on your soul.

You did a good job doing absolutely nothing. Keep it up.
