>>508318088 (OP)15-25 is the sweet spot for training a good soldier. This 10 year period is when the male body is at its peak and is capable of being molded into something amazing with very little effort.
Why? Because 26 is the cut off for biological immortality. essentially your body can produce cells faster than it loses them up to that point in time, which means you recover from injury, sickness, and stress significantly faster. its also easier to build muscles before 26. An older person also has more life experience and wisdom which makes it harder to mold them into the propper mindset.
If you are a videogame playing neet, you can see this play out in real time. Your hand eye coordination starts to slip around 26 as you lose the edge of youthfulness. You start to miss shots you'd never miss before. You start to suck at playing vidya. This is true for being a soldier as well. What makes older soldiers better than 18 year old grunts is combat experience and tactical knowledge, but if there was a way to keep soldiers at 18 forever, the military would totally do it.
