During the Battle of Magadishu (1993) multiple Black Hawk helicopters were shot down and a group of soldiers were pinned down under unexpected enemy resistance.
Air support was provided by both MH-60 and AH/MH-6 helicopters. However, these are relatively light forms of air support.
Aircraft with more firepower, such as A-10's, capable of loitering out of harms way from unguided RPG's, appear to a layman such as myself as a vastly better solution for providing air support on demand.
Other aircraft such as F-16 or F-15 also appear to be capable of providing much more powerful air support than what the MH-60 and AH/MH-6 can perform -- without taking much if any risk doing it.
Finally, why was artillery not used?
It seems strange that nothing of this sort was available within the combat range of any of the aforementioned aircraft. So I can only assume there's some other reason behind why this wasn't provided. What was the reason?
