Ah soul, bless you for being so woefully ignorant.
My y8 was in her 7th (state or free local international) school (and her younger two siblings obviously following in her footsteps) as we chose to keep our children with us. We have lots of friends of all ranks who chose continuity of education over keeping the family together, but the choice isn't easy for anyone involved. Every child needs different things - some children struggle hugely with moving. (There is a whole cohort of research on armed forces children and education - there's a much higher likelihood of sen etc, and a much lower likelihood of any issues getting properly assessed, diagnosed and supported, due to the fact that when you get to the top of the assessment waiting list, you are moved 250 miles, and get out back at the bottom again). Schools are finally realising this and now have to report their levels of armed forces children, and the army families federation and ssafa have been working towards allowing armed forces children to 'port' statements of special educational need, for example, rather than have to get reassessed everywhere they go.
My dd2 has cerebral palsy. No boarding school will touch her. Want to know how easy it is to move abroad with a child with a disability and set up new health and education? Bwahahahaha ha.
Oh, dh got himself blown up, as well, when we were overseas. Wasn't expected to survive, so we had all that hoo ha.
There are a myriad of reasons why armed forces families choose continuity of education for their children. All armed forces families, not just senior officers. A Sergeant and a Brigadier have the same basic decisions to make. Can I bear to be without my kids? Am I being selfish to drag them around the world with me, when I have no choice where we will go, and how often? Am I damaging their education by doing so? (When we turned up in one particular location, I was told 'well, you just have to think of the schooling as an opportunity to star in a movie for a year - they won't learn anything, but it's a fun change'...
Oh, and wives who don't work? dear soul, please do take a look at the huge body of research that exists around spoue's careers of serving personnel. RAND is a fine place to start, but Kings is more UK centric. A little like continuity of education, there's no such thing as continuity of career (or indeed of spousal education - try finishing a masters when you get moved every year) when you can get moved at any point.
In short , you know not of what you speak. So, shush, really. You're embarrassing yourself by continuing to display your ignorance.
