All of these are from Harrison-334, my SPARTAN-IV OC.
"ONI can keep their damn secrets for all I care. Me? I'm just content to shoot alien bastards and keep humanity safe. That's all I care about. Besides, we've all got something to hide. It's best not to pry. Take it from me - questions get you killed."
"It was hard to be a Lone Wolf sometimes. Before my squad, I had to look at everything in a watery grey to keep myself from vomiting at the things I've done. Splitting skulls for ONI, getting blood on my hands so the suits at FLEETCOM wouldn't have to, left me wondering why I did it in the first place. I guess I'm just glad to have my team to keep me straight."
"I've pissed off the brass a few times. I don't give a damn what the Admiral has to say - I'm taking that gun."
"I can't afford to die. I got the entire human race counting on me. If I give out, then everyone I care about gets screwed along with me. I can't let that happen."
"Lay down in the mud. Sit there. Still. You move, you die. That's a tough lesson to learn, and I've lost too many comrades because they couldn't handle the pressure."
"I don't miss being an ODST any more than I miss being a regular Joe getting coffee in a run-down apartment on Earth. I get nasty looks from some of the Helldivers - they think I'm a traitor because of the age-long rivalry between Spartans and ODSTs. When one of them tries to start something, I just say, 'Look at Buck,' and they back off just fine."
"Guns are like pets. You take care of them, keep them in good shape, they'll do the same. You neglect them, refuse to treat them well, you're screwed."
