there's a reason why DXOs or military personnel are paid a slight premium as compared to their civil service counterparts. reasons i wont delve into. just note that DXOs are subjected to military laws also and do perform duties beyond their job scopes. defence is not 8 to 5. but maybe passport making is.

and of course, if MINDEF reviews that the salary is market competitive, then there wont be any adjustments. but based on my opinion, there would likely be as the civil service has had a increment. to have that premium, MINDEF would probably increase the salaries a little. mainly to be competitive and counter inflation i guess?
