"At least it'd make it obvious how many civil serpents now inhabit the place!"
Actually Beags I'm going to have to burst your bubble, the total CS population of MB is a little over half (roughly 2000 of the 4000 odd that work there). Bearing in mind that most of this lot are admin clerks, security guards, cleaners and so on, I'm afraid that most of the people working there in a defence policy capacity will be in uniform.
EDIT - having read the article, there appears to be some confusion with BA - they already offer a 10% discount to military personnel, despite claims to the contrary in the report.
