Teetering head
Got there first d@mmit!
To add a bit though (and at the risk of abuse from ABIW and Beags!):
The Services are NOT like "some companies"where you get to "concentrate your core competencies in a going forward manner and screw all your mates who are trying to do the same then go home at 5 and never have to give a bit extra (like being on QRA on a Sunday for instance!). The Services are a team game, and it often demands huge sacrifies of you and your family, meaning that you have to want to be there. If you think the life is easy and its just another job with wings on, all you'll be doing is joining the other chisellers that take the money but still whinge and make life less enjoyable for those of us that actually want to be here.
Go join "some other company"
And another thing - its retention not retainment!
