Hi, I am the White Mamba Overlord of our group the ODSM.
We are not a clan, and we don't play the game for competition. Instead we play for fun, and to hang out with friends. If you are interested in joining go to our group homepage and sign up. Membership is open.
We are mostly a Halo 3: ODST group for help with achievements and stuff, but we also will play a lot of Halo 3 matchmaking.
Something tells me that these 2 people aren't even spartans, but instead they are pelicans. The word "Sierra" dosen't have to meen that they are spartans just because MC was called Sierra 117 in Halo 3. Sierra is in the Phonetic Alphabet as the letter "S" just like Alpha is for "A" and Bravo is for "B." As most of you already know in Halo CE one of the pelicans was called "Echo 419." Echo = E.
The first one says "This is Sierra 320 prepped for combat insertion." I think this sounds more like a pelican stating that they are ready for lift-off, and not a spartan.
The other one says "This is Sierra 259. We've got spartans on the ground sir. We're not going anyware." I believe this is Fred telling fleetcom that he and his spartans are on the ground. He probably wouldn't call himself Spartan 104, but instead by the pelican that he and the other spartans were on. It would be easier for fleetcom to go by that i would think.
Well that's my theory of Sierra 320 and 259. Tell me what you guys think, and please state your theories too. I would love to hear them. =P
UPDATE: Thanks to "Xalkin0" I have a better idea of who Sierra 320 is. I believe that this is Linda talking on the pelican that her, John, and James I believe are taking to a space station to destroy the Circumference's navigation data.
As far as I can remember Linda has an accent similar to the woman in the teaser.
I am going to re-read FoR to refresh my memory. As soon as I'm done I will update again.
