Geardos of the world unite.  Off Duty Gamers brings you a breakdown of the gear pictured in the teaser art.  Can we expect to see it in-game, or just a bunch of hype?  Whatever the case, an impressive amount of research:

I think they just wanted the soldier to look as realistic as possible.
 
Its pretty terrifying that someone looked into all of this.

wow that was amazing ! 
 
some people are crazy detail experts :O

I stopped reading when it said helmet.

Kudos to Dice for giving such attention to detail.

You just have to know soldiers to understand.  It's pretty common to compare or critique gear. "

Yeah, don't make any assumptions from this...

Yes.. they love to compare the size of their.. gear. "

Seriously though, I really like the eye for detail and realism. Infinity Ward almost always went totally geardo when designing character models and those were amazing, and I'm hoping this sort of thing will add to immersion and overall awesomeness.
