I'm working with broad strokes based on reading the book a few years back and wiki, so bear with the inaccuracies.
UNOSOM tried to go after a tribal meeting with gunships that plastered the area but didn't bag the Persons of Interest. Whether you say the intel was bad, execution was bad, timing was off, whatever, it clear nobody in DC wanted collateral casualties after that.
That's why Garrison called in Delta and Airbone to try stealth instead of firepower. As mentioned upthread, they were successful at bagging junior lieutenants with the scoot, scoop, and run tacs using helos to distract from ground attacks, ground attacks to allow air drops to assault, bag, and bail.
However, trying to do that in the middle of Mog after the Americans'd tried that multiple times allowed Aidid's crew to monkey-wrench the aerial assualt. Technicals and militia were able to keep the HMMV ground attack at bay for hours when tanks were needed to smash the barricades.
I mention Spooky (AC-130) and Apache gunships because they could've blasted "technical" barricades clear in seconds. I'd have loved to see the mob go after the downed pilots if Spooky does a run or two over them or a couple of Apaches are overwatch.
It'd be a massacre and all over the world's news- UN forces massacre hundreds of "civilians" during humanitarian mission. Never mind dozens of militiamen were firing AK's, RPG's and RPK's using civilians as meatshields.
Let me make this perfectly clear:
I don't revel in firepower for firepower's sake or more Somali dead but compared to the slow-motion tragedy of famine and civil war gripping Somalia, a few more hundred more Somali dead and Aidid either dead or in custody would've saved thousands of Somali lives.
IMO worth doing it.
