Why 405th?

[MysticLegend]

Just rewatched the E3 video for Halo 2, and realized that they mention a Garcia from 405th.
Would that have anything to do with the decision for this forum's name?

I'm pretty sure the "405th" is the division of the Marines the Spartan's belong to. I could be mistaken... My Halo history isn't so up to par...

Oops....jumped the gun again.
Took 2 minutes of reading and googling to figure it out....

Halopedia Rules

The 405th is based out of Diego Garcia. They arrived on scene during the Covenant attack of Mombasa, Kenya on Earth. They went on to fight on the city streets of New Mombasa valiantly[1].

The 405th assisted the Master Chief in the destruction of a Scarab that was moving through the city. Members of this unit then traveled to Installation 05 along with the Chief aboard the UNSC In Amber Clad.

So....they exist, but aren't a Spartan group.
*insert 20 minute gap*
Actually, I couldn't find anything that described the unit they belonged to. Considering that there were only 33 of them in combat duty, and were generally kept together and moved as a unit (starting off), I bet they were their own unit.
