He is the reason the 5 year RoS came in, to prevent people from doing just 2 years.
Not the case - the 5 years RoS was in from the start of PAS when it was introduced in 2003 to those of us who were already Spec Aircrew - in fact those that did not have 5 years left till their 55 point were not allowed to go across to PAS.
You
can leave before the 5 year RoS point but you get no pension supplement - for those who haven't bothered to read the links above, this is from the JSP:
PAS/PES(A) OF3s who exit the Service prior to giving the requisite
5 years of Service on the PAS/PES(A) will receive the standard CS
representative rank based pension.
