Per a "disseminate to all" email from our commander, pretty much every officer aviation field in the USAF is very undermanned. To add to the burden, the AF wants to double the number of UAV squadrons in the next few years. Some airframes are doing 6 months on/ 6 off rotations to various parts of the globe and others are 6 months on/ 12 months off; both still have their one-off deployments, schools, etc. to handle in the "off" period.
Some are whining about it, some are keeping it into perspective, but it drags everyone down at some point, even the latter group. The common refrain from just about everyone is "no end in sight." Sure, SOF has a much higher tempo, but they are specially selected and trained with high levels of motivation. The rank and file "warriors" are anything but and it shows...even if their "deployments" are to places like Al Udeid or other comfy bases.
