Don't let our whinging put you off. Yes, conditions have been eroded since we joined, but now that many of the benefits are gone, they can't be eroded away from under you as you will never have experienced them. Bases are being closed, but bases were being closed before any of us joined (even the cold war warriors like myself) and, if anything, the rate of closures has slowed down over the years - a trend that is bound to continue as the total number of bases reaches a minimum level. As for reduced spending on facilities, despite all the complaining, facilities are far better now than they were 20 years ago - 8 man rooms again, anyone? Every sqn I was on for many years was housed in WW2 'temporary' accommodation - 47 Sqn only moved to a brick built facility a little over 10 years ago. Things only used to be improved when the occupants of the buildings did it at their own expense - something that changing attitudes has reduced or stopped over the years.
The things you read us complaining about aren't things that should be putting you off as they are complaints about things that will not impact you if you were to join now. Instead, you will be able to amass your own set of compaints over a career that you can highlight uselessly to candidates in your turn!
