There is nothing new or shocking about this. The civilian leadership demands the US Military send X-Amount of advisors somewhere,and if the military doesn't have that many trained people ready to go,they send who they have that is the closest thing they have to trained.
The US Military follows orders,they don't create the orders. That "service" is done by the clueless fools who are elected and looking for positive press releases to show the voters "they are doing something".
