A few questions, 1. First of all, why is guard bumming looked down upon? 2. I would like to be able to fly as much as possible while serving and realize reserves is the way to go but I would like some help understanding the difference in potential hours someone who guard bums a c-17 vs kc-135 could earn. 3. Lastly if down the line if I wanted to change locations, how easily could someone switch from let's say a reserve kc-135 unit switch to a guard c-17 unit or vice versa?, or is that just plain stupid and not possible?, thanks to anyone willing to take the time to answer my questions (:
