I'm sure that more than just APOs are on income support or whatever with families. And as an aside to this subject wasn't part of the Bett shambles the renaming of MQs to FQs so that those in a stable long term relationship could occupy them?? Well where I am (singly mind) married couples have to wait for quarters that are far from satisfactory, let alone have spare for "modern families"...
It is ridiculous, we dont pay, house or in anyway look after the people that are expected to spend all the year away from their families anyhow!!!
Retention - I cant see the problem
