Yeah but as a line they are still in service, right? The A-10 as a ground support platform I mean. Eventually though, as mentioned in the article, the entire fleet of A-10s will be decommissioned from service with the USAF.
If the army does pick them up, as Ryllharu mentioned, they could get another 30 years of service out of them. I'm surprised the Marines don't take them. They still fly some old helos and use Vietnam era M-16s.
