Artyhug,
Actually the ROE requirements were more stringent in Fallujah 04 than Mog and FW air was employed along with RCAS in Fallujah.
This is not to say that someone up the chain may not have called off any/all FW strikes as was done on say the O’Grady Exfil.
Double zero has missed the mark on the ability of armor to operate in built up areas, it has been done successfully and to very good effect.
