Is there any Socom 2 like games for 360 online?

Which would be the closest game online like Socom 2 for 360.

Also i have a few questions

on Rainbow six can you switch to a third-person view?

to answer your first question i would have to say GRAW 1 & 2 since they seem kind of similar IMO

to answer your second question it only switches to third person when you take cover or are spectating, not when youre running around
