I think being a career soldier is a very good profession

Of course there are downsides, but I think it's one of the best workplaces and jobs you can get with those specs.
For example, if you only have a high school diploma, things like working in mobile phone sales, restaurant serving, or food delivery are quite common.
The best-case scenario would be a production worker at a large corporation.
But for non-commissioned officers, you get a pension and it's actually quite decent.
As long as people aren't making ridiculous comparisons to fraudulent professions, it's a good job.
Officers are usually Captains in their 30s, and with an annual salary of around 50 million KRW, it's similar to large corporations.
Also, while the mandatory retirement age is relatively early, many are re-employed as civilian employees in the military.
