To test whether the more than 50-year-old plane still had some fight in it, US Central Command (CENTCOM) sent two OV-10s to Iraq, where they flew 120 combat missions as part of Operation Inherent Resolve, with a 99% success rate.... Capable of carrying 3,000 pounds of ordinance, the Bronco can carry an overwhelming assortment of firepower for it’s small size, including either four 7.62mm machine guns, four .50 caliber machine guns, or a pair of 20mm cannons in addition to a loadout of rockets, missiles, and bombs as needed for the day’s mission...Quite a bit of video at the link.
One more fun trick the OV-10 does it drop a 5-man Special Forces ODA out the back.
It lacks the A-10's survivability, but it does have a lot more flexibility. Boeing has been thinking about restarting production anyway, as it's cheap enough that lots of countries can afford it. As the initial article points out, it only costs $1,000 an hour to operate, compared with $40,000 for an F-15 (another fighter commonly bought by Third World American allies). For sake of comparison, the A-10 comes in at $11,500, and the F-35 at $39,000 an hour (well, or so they say -- when they get them working, we'll see what the cost really is). So the OV-10 is even cheaper to operate than a Predator drone.
