"That's only the Official Story according to my file."
"You see that artillery shell didn't just hit my unit, it also hit a small civilian shelter we had just discovered."
"We were about to start the evac when the bombs came."
"But thats still not even the worst of it."
"Before the first bomb hit a young lad walked up to me, and handed me something, a little silver coin."
"He asked me, Please make the bad robots go away."
"Heh, runt wanted to pay me to kill Clankers."
*Sigh* "He didn't make it."
"Bombs hit and the whole civi shelter fell on top of our heads. Whole thing went Off the Record."
"Damn Clankers, the gave me the title of ARC Trooper for all that but really I was just trying to survive so I could kill just one more Clanker."
"Kept the coin though. Everyone says it's my good luck charm so they started to call me Coin."
"But to me, it's just a reminder of what I'm really fighting for."
