I think you should take an advice from someone who has switched from army to civil service. That person can draw a better comparison between these two different careers or more precisely two different life styles. Every year, the quota of army in civil service is filled by the recommendation of GHQ, which you may know as well. So, there's something catchy that makes army officers want to join the civil service. If we take the top three occupational groups (PAS, FSP, PSP) of civil service into consideration then they seem to be a bit more rewarding, lucrative and own a special status in our society and in the eyes of public as compared to army while keeping the "power" factor aside. Among the aforementioned groups, PAS is said to be the most loved one among the aspirants. It lets you push yourself to the policy-making level where you can bring change for the masses.

You see, there's no such thing which you can call perfect. Every profession has its pros and cons. So, before you decide anything, just consider the dominant factor that makes you want to join civil service. And, the written exam is exempted for armed force personnel which is quite a hard nut to crack for the aspirants like us. You seem to have an advantage over us in a sense that you don't have to appear for the written exam, which has become quite difficult to pass since the syllabus was revised. Anyhow, I would like to suggest you to meet someone in person who have had a taste of both of the things, so that you could take an objective decision.
