Marksman, did you catch the beginning of all this? Air Force guys are complaining about the quality of their laundry service and volleyball equipment while deployed in trashcanastan. We're simply laughing at them for whining.
Besides, intraservice rivalry is a simple fact of life, and actually does quite a bit of good when properly channeled. I'ts an inescapable fact of human nature that a group bonds better and becomes a more cohesive and effective unit when presented with "outsiders". REMFs will always consider line grunts to be uncouth, guys at the sharp end of the stick will always consider REMFs soft, yadda yadda yadda. Those who get their panties in a bunch over it need to lighten up, and take in the bigger picture.
Good luck on your enlistment, whatever branch you go with. Do your research, get everything on your contract before you sign, and remember, YOUR RECRUITER IS NOT YOUR FRIEND!!!
Take care.
