Ya Better Ask !!!
If you're thinking of joining - the COS18 info given above is a typical glossed over parlour trick...
ASK QUESTIONS !!!!
How much does schooling cost for children (ESF etc)
What are my medical benefits AND what are the limits ?
What is the Dental Coverage and what does it cover ??
Are my annual travel tickets (FOC) for my family and myself to travel home "Confirmed NOSUB" ???
If you don't ask, don't even think of bitching about it at a later date.. You own it.
