-Living in Clovis, NM is like being deployed overseas to Afghanistan/Iraq, but without the deployment pay, it actually does resemble Helmand Province quite a bit on dusty days. Also, the locals can be pretty insufferable, crime is high despite being a rural town, and the nearest cities/airports are 1.5 to 4 hours away. It might be more bearable living here if you have a family, hobbies to distract you or you're just a homebody.
-Lack of deployment opportunities. It's supposed to be 90 day rotations with 1-2 deployments a year, but the Afghanistan pullout has shaken things up a bit. You're probably looking at a deployment every 1.5 to 2 years now. If deployments ever significantly picked up again, this would be a great gig, but being stuck in Clovis all the time just feels like some cruel form of punishment.
-Feels like the Cannon AFB (Clovis, NM) shop is the "B team" compared to the other shop at Hurlburt Field (Fort Walton Beach, FL). Less staff, equipment, parts, deployments, no shift differential pay, general pay being lower (cost of living difference) and a tremendously worse location etc.
