There are some other symbols on the Iraq maps, so I'll be looking for more references. ALso, I have zero working knowledge of our various units hardware and troop strength, so can't interpret the maps well. But the maps beat the tar out of trying to interpret a text description!
I think the significance is that the "Naked X inside" means only infantry. The armored stuff may be, but isn't necessarily, accompanied by infantry. I see one of our units having a combination of infantry and Air Assault (close air support, Apache probably).
Do you see the 101st north of Med2? Holy sh!t. They were in the same (general) location yesterday.
Now I have developed a habit of chacking for new maps . . . LOL!
