It is not true that you need fewer skills in the military.
In the military it is often your skills that keep you alive in a dangerous situation.
It is fair to say that the military is willing to train you , but for the last two decades thay have become increaseingly choosy and prone to reject to hard to train.
If we were to return to the more lax standards of the late seventys ,when I joined, we might more easily meet quotas for recruiters , but we might have a less usefull force.
