Sorry mate I am not Space but I will throw a figure out there.
From what I know about what I am paid and what my mates are getting, a senior FLTLT will crack 6 figs sometime in the last few years of ROSO.
Most guys at end of ROSO are on about 110K.
I am not even going to try and speculate about how much medical and all that stuff is worth. Housing allowances are probably worth about 10-15K pre-tax per year.
