"At the time of the rescue mission, Major Ye had already retired from the military and become a successful businessman. However, he still went on a mission to rescue the scientist. This shows that even though he had left the military, he had not stopped serving the people.
As long as his country needed him, he would do whatever he could to help. That was a very eye-catching mission, which is why it's known by many people, but in the last two years after his retirement, he had gone on several missions, off the books.
Now, taking that as an example, are you still worried that you won't get to help regular citizens once you leave the military?
As long as it's a mission that doesn't involve fighting for power, we can help.
In fact, we can take on such missions without the need for others giving us orders that we cannot disobey.
If we were not in the military, most of our brothers wouldn't have died just to complete the mission.
