Any advice on what kit would give me the classic, most up-to-date example of an Abrams tank being used in Iraq right now?

I know there may not be a straight answer to this question, but if an infantryman were to see an American tank rolling down the dusty streets of an Iraqi city or village this very day, what variant would he most likely be looking at?

My aim is to model "today's M1 Abrams", and with M1A1's, HA's, and M1A2's [along with all the TUSK kits, additional armor, and added anti-IED antennae], I'm at a complete loss as to what is really on the streets these days. I'm guessing there might be a mix, but if one is most common or the standard that units are moving towards, please enlighten me!

Here's a M1A2 SEP V2 (?) at FOB Hammer, May 5 :

But you can come across M1A1s as well...
