The Battle Creek Reds are lead by The Red Zealot
The Battle Creek Blues are lead by Hambone
The offical information follows.

Name: The Red Zealot
Status: Alive {unforutantely}
Armor: Red
Comments: This particular zealot was fed a lot of sugar as a kid... a looooot of sugar. He was fed so much sugar, in fact, that he became mortally addicted to it. Today, he can't go more than two hours without sugar, or else he goes in to a withdrawal seizure. Of course, always being stoned on sugar has a rather curious side-effect: he's always hyper.
When you spend all your time running around and hitting things on a perpetual sugar high, people take notice of you. It just happens that one day a Spartan recruiter spied our overzealous friend beating up a tree with his face, and winning, and the recruiter decided he would be the right man to join the Spartans. So began his intense military training.
Unfortunately, none of The Zealot's Sargeants were able to control him. Between his constant hyperactivity, and his persistent belief that he lives in a Kevin Smith movie, the drill Sargeants were forced to give up on making him a proper, bonafide soldier.
Instead, they dropped him in Battle Creek and pumped him full of experimental drugs meant to accentuate the personality traits he happened to have in abundance already. There he was able to run freely and give didactic speeches to his heart's content. He felt so comfortable in Battle Creek, in fact, that he managed to successfully capture the blue flag!
But alas, all good things must come to an end. Shortly after gaining the flag, it was taken from him by the Blue forces occupying Battle Creek, and he was forced to start over from scratch. Even now, at his advanced age of fifteen, he plots his revenge... At least, he did until he was brought to Sidewinder and blown in to the future. Then he was murdered in the side with a sword. Upon his death, he saw the Flag. It was so... flappy. Rest in Peace, Red Zealot.
That is, Rest in Peace, until that trumpet player starts up another round!

Name: Hambone
Armor: Blue
Status: Alive {unfortunately}
Comments: Hambone (centered under the targetting reticle for convenience) was abandoned in the woods as a child and raised by bulls. When the Spartan Forces were doing their sweep of the community to find recruits, they saw Hambone attacking a clothesline by running in to it head first. They immediately knew they'd found their man, and took him off for training on the spot.
His training officers tried to find some way to immediately use his talents, but just couldn't do it. When you're raised by bulls, you always act like the bull. Your very life revolves around being a bull, and it's all you know how to do. No matter what anyone else did or said, Hambone always attacked any items of persistent motion.
It was so hard breaking Hambone of his instincts for attacking things that moved, that Spartan Command decided to insert him in to their experimental program on Battle Creek. They pumped him full of drugs and set him loose on the world, where he was an instant hit. Wherever a flag is to be found, there'll be Hambone, trying to maul it with his head.
Name: The Battle Creek Reds
Armor: Red
Status: Very much alive
Comments: Several months ago, Red Command decided it would be a good idea to pump several dozens of soldiers full of an experimental drug designed to increase aggressiveness, and put them in Battle Creek to observe the results. The result of this experiment was the Battle Creek Reds, and it wasn't pretty.
The drug had three unexpected side effects. First, it raised the voice of anyone who ingested it by no less than one full octave. Second, everyone who took it became insanely hyper, as if on a permanent manic swing of bipolar disorder. Third, death was no longer permanent when accompanied by the playing of the song Reveille.
That's right, as long as there is someone around to play Reveille, none of the Battle Creek Reds can become permanently deceased. When it was discovered that Blue Command had been testing a similar drug on the same land region, things went from bad to worse, as a fourth side effect was discovered: the emergence of unbelievable amounts of stupidity.
As it stands, the Battle Creek Reds are locked in permanent combat with the Battle Creek Blues, constantly being killed and resurrected to continue the pointless bloodletting. The Reds have only one advantage over the Blues: Hambone. Hambone acts as both inspiration and abusive Uncle to the Battle Creek Reds, giving them a slight edge in the endless conflict. Whether that will be enough, only time can tell.
Name: The Battle Creek Blues
Armor: Blue
Status: Very much alive
Comments: Sometimes, Vic has entirely too much influence over the happenings of Blue Command. One day he was passing around his special brownies, when he managed to convince everyone else at Blue Command to inject half a dozen soldiers with a brand new drug and drop them in Battle Creek, just to see what would happen. The results were found to be most amusing.
It turns out they gave their soldiers the wrong drug. Instead of the anti-wrinkle agent, they received an insanely high dose of a very potent anti-depressant. This was how Blue Command learned what happens when you give in to one of Vic's ideas. However, what was witnessed coming from Battle Creek after the troops were dropped off was something worth taking note of.
Nobody had ever taken this particular drug in such high quantities as the "chosen" soldiers of Battle Creek, and some very interesting effects were revealed from the mistaken experiment. Everyone seemed really optimistic for some reason, and full of a seemingly endless supply of energy. One slightly frightening side-effect was revealed as well: Reveille could bring them back from the dead.
That's right, as long as someone's there to play Reveille, they need not ever die. The General at Blue Command immediately realised the problem with this situation, and recalled the drug for immediate destruction. To this day, the only remaining trace of the drug is within the six unlucky soldiers in to whom it was injected, locked in an endless battle with a Red army in surprisingly similar circumstances.
All anyone can do now is watch the perpetual carnage, and wait for that damn trumpet player to get hit by a stray bullet.
