From a retired USAF pilot who flew Broncos as an FO/FAC...
FAC and artillery spotting...No warning or countermeasure systems...Low and slow...
Solid airframe that could take damage, 2-man crew, high viz cockpit, rear cargo area and short/rough field capable, Navy used ‘em off carriers I’ve read...
Likely never utilized to its full mission potential...Might be ideal for anti-ISIS missions...
Probably much more survivable with today’s countermeasure systems and cameras. One of the factors making lighter aircraft more viable is the return of the 250 lb class bomb. It is also one of the errant ways people criticize the F-35, because it will be some years before those weapons can be carried internally. The design of the F-35 weapons bay didn’t include those weapons because they weren’t in development yet.
