Beags and guys - thanks for the replies.
At the moment my game plan is to stay in the service until my 38/16 point.
I am currently 31 yrs old - have got about 3000 military, of which about 1000 hrs are PIC on one of the approved ME types.
My understanding of LASORS is that all I need to do is the Air Law Exam, a Class I Medical and arrange for a CAA IRE to 'observe' a military IRT on my jet.
My question is therefore : do I wait until nearer my exit date before bothering with my licence due to possible 'expiry issues' when I disappear into ground tours or get it now and just attempt to get into a flying tour to keep it current before leaving??
