In that case, again, depending on when you want it to depict during OIF, you can get either the Tamiya M2A2 ODS kit (#35264) or Academy's M2A2 OIF kit (#13205). Both build into a Bradley used in Iraq from about '03-'05. By the way, M2A2 ODS refers to improvements made to the Bradley from lessons learned in ODS, not a vehicle as seen in ODS.
The Tamiya one represents a rebuilt to latest standards M2A2 ODS version as used by 3 ID in the initial invasion (March '03). It has most of the ODS mods that were seen at that time, but still shows parts that were removed or changed as well. It also has you adding obsolete parts such as the flotation system rods on the rear and left side of the hull.

Tamiya M2A2 ODS
The Academy M2A2 OIF kit represents a new-build M2A2 ODS from about the same time as Tamiya's. It has many newer features that Tamiya left off, like the new driver's hatch hinge, anti-foul bars in front of the driver's hatch, new lower front glacis plate, etc. It also has nicer side armor, sprockets with lightening holes, and better details in some areas. It has incorrect, old-style, triangle block track in the kit though. The triangle block track hasn't been used since the mid-'90s. Furthermore, Academy molded the track incorrectly as well, with the pads being molded 180 degrees from how they should be. AFV Club makes a great set of indi-link, square block, plastic track for them though.

Academy M2A2 OIF
Neither comes with PE. Eduard does a few good PE sets though, one being a full turret interior. Legends and Voyager also have PE sets for them.
The M2A2 and forward kits deleted the interior that came in Tamiya's original M2 kit (and Academy's copy). For an interior, you can find either older M2 kit on eBay pretty cheaply and use the interior out of it for an older M2A2 ODS w/out interior seating mods (changed to long seats along the hull like an M113 with full mods), or use it as a base for a new interior.
If you want to build it from later in the conflict, wait for Meng's forthcoming M2A3. It represents a vehicle from about '07 forward or so. It is the latest version with an added Commander's Independant Thermal Viewer (CITV); Driver's Vision Enhancer (DVE); Bradley Urban Survival Kit (BUSK) III which includes ERA tiles for the hull and sides, commnder's shields, A/C units on the rear hull; and full IED jammer equipment. It is also supposed to have a full hull and turret interior including engine and tranny. It is due out in Jan '14.
