Spartan Ops Easter Eggs

Red vs. Blue Radios are Easter eggs featured in Halo 4's Spartan Ops mode.

Description
Certain episodes of Spartan Ops' first season have hidden UNSC radios. Shooting these radios will cause them to play Red vs. Blue's opening theme. In addition, as a consequence of triggering the easter egg, dialogue from key moments of a chapter will include humorous dialogue from the series' cast. Finding one of these easter eggs will award the Roses vs Violets achievement.

Core
While Crimson is defending the artifact.
 * Commander Palmer: "Commander Palmer to Fireteam Castle. You're on Spartans, Dalton's got targets for you."
 * Caboose: "Um, the regular radio guy isn't here right now. Sorry."
 * Commander Palmer: "Fireteam Castle, this is Commander Palmer. I need an ETA on clear skies."
 * Caboose: "Seriously, the regular radio guy said he'd be right back. He's in the bathroom."

Gargarin
Crimson activates the first computer.
 * Caboose: "What does this button do?"
 * Church: "Caboose, don't touch anything!"
 * Caboose: "But I'm great at buttons. Oh, look at that explosion!"

Recording ends.

Crimson activates the second. ''Recording ends. Crimson activates the third.''
 * Church: "Great. You broke it."
 * Caboose: "No. The fire broke it. Oh, look, I'm on fire too. Awesome."
 * Grif: "Hey, Simmons? What do you think this thing does?"
 * Simmons: "How should I know? It's a giant seamless alien monolith with a single holographic button. It could be anything from a giant microwave oven to a weapon with enough power to-"
 * Caboose: [screaming] "I'm on fire!"
 * Simmons: "Wait, is that Caboose?"
 * Grif: "Probably. He's on fire."
 * Caboose: [screaming] "The armor! It does nothing!"

Shootout in Valhalla
Pelicans fly in with Mantises. Pelicans drop Mantises.
 * Simmons: "Hold tight, ground forces. We are inbound with reinforcements. Don't wanna give anything away but you're gonna like them."
 * Grif: "It's giant robots."
 * Simmons: "Grif! You ruined the surprise! You have no flair for the dramatic."
 * Grif: "They're in battle, idiot! How dramatic do you want it to get?"

Rally Point
When Crimson reaches the waterfront tower. Pause. Pause Pause. Pause.
 * Vic: "Hello? Hello? Commander Palmer, dude? Do you read me?"
 * Commander Palmer: "What are you even doing?"
 * Vic: "I thought you saved my number last night, dude. You were really killin' at the karaoke if you know what I mean, dude."
 * Commander Palmer: "Miller? Status?"
 * Miller:" Working on it, Commander."
 * Vic: "Sheesh, Commander Buzzkill. I'm going to 80's night tomorrow so let me know when you save the universe. Asta liago. Liago bye bye."

Spartan Thorne
When the equipment drop comes. Several Gravity Hammers marked "Sports equipment" are dropped.
 * Sarge: "I heard you need a lift, but all we've got are these guns. I suppose you could assemble some kind of gun-like vehicle with the parts... But who knows what the insurance rate would be on that bad boy."
 * Sarge: "Dammit, Grif! You dropped the cargo! Now how are we supposed to play Grifball?"
 * Grif: "I think the bigger question is, why was a military vehicle sent into battle with sports equipment?"

Shut Down
After Crimson has reached the nukes.
 * Sarge: (mocking voice) "This is Corporal Switchback to Infinity!"
 * Commander Palmer: "Go ahead, Switchback."
 * Sarge: "Hey Infinity, is your slipspace drive running? Because you'd better go catch it!"
 * Commander Palmer: "Crimson, you're the closest responder. Fall out and help Switchback."
 * Grif: "Babba bouy! Babba bouy!"

Engine of Destruction
When Crimson disables the warhead in the server room.
 * Simmons: "This is Private Simmons! There was a big firefight down here, the engine's all shot up! We need a maintenance crew ASAP!"
 * Miller: "Keep it together, marine. Spartans are on the way."
 * Simmons: (sarcastically) "Great, more people with guns! I'm sure that will fix the engine!"

Majestic Rescue
When the equipment drop comes.
 * Miller: "I'm having Dalton send some more supplies your way, Crimson."
 * Caboose: "Six cases of headlight fluid and elbow grease inbound now."

The Hammer
After Crimson activates a Hawk squad IFF tag. Plasma fire. Energy sword. Recording ends.
 * Roland: "Alright, I've got a recording from a Hawk IFF tag, playing it now."
 * Elite: (speaking Sangheilian)
 * Church: "Okay, I have absolutely no idea what you're saying."
 * Elite: (speaking Sangheilian)
 * Church: "Dude, listen to me! I do not speak alien!"
 * Church: "Aaagh! This is such BS!"
 * Church: "Ugh... blarg!"

Seize the Power
When Crimson is about to board the Lich.
 * Miller: "Crimson, I'm not saying it's even sane. But get on that Lich at any cost."
 * Agent Georgia: "Cool, jetpacks. Those'll get us on that Lich or my name isn't Agent Georgia."
