Looks like this is a small unit armed with Humvees and Stinger Missiles. Looks like regular Humvees Not Humvees armed with a pedestal mount for stinger missiles (see the Avenger web site below).
I could see if their were armed with 1960 era Vulcans or 1950 eras dusters. The Vulcans were 20mm Cannon and the Dusters have 40mm Cannon, both of which have been used to defeat attacking infantry formations (both were used as such in Vietnam). I could see the Avenger system with its 50 caliber machine gun (Harding hitting than a 7.62mm gun) but no were near the Volume of fire of the Vulcan, Duster or even the 7.62 mm machine guns already in Iraq.
Thus the 202nd was NOT mobilized to provide suppressive fire in Iraq, it just can not provide such fire. Thus why is it going? Lest look at some "reasons":
1. Bush has already wrote off Illinois (or that part of Illinois where this unit is based) and thus prefer to call up this Illinois unit rather than Police, Armor or Infantry units from a State (or area of a state) that Bush (or a GOP member of the House of Representative) may be able to win in 2004.
2. There is a fear of low flying Aircraft somewhere operating below our air cover. The problem with this is how would a ADA unit help when such an attack would have to be so low to escape detection that people with rifles could shot it down? Now, none of the Countries around Iraq is permitting us to operate from their country. We do have some operations out of Qatar but the Carriers are gone. Is the fuel problem in Iraq so acute that we may have to cut back air operations? If you cut back Air Patrols than placing a ADA unit makes sense. Also makes sense if you want to use the Air craft to attack someplace else (i.e. Iran or Syria)? Iran may attack back in an area where we have no Aircraft thus ADA is needed.
3. After a careful review of the situation the 202nd was viewed as one of the best trained National Guard units and as such quickest to get on line in Iraq.
4. The 202nd has more up to date equipment than comparable Infantry Units.
5. To provide Cover to call up even more units in a state Bush has written off in 2004 (A variation of number 1 above).
I lean to number 1, with number 2 being used to justify calling out this unit.
