Have you read the article? It says the effective recruiting pool is 1.7 million, and the goal is 180,000 recruits. That means you'd need to convince every 1 in 10 eligible person to enlist. Even if the military was a glory-filled job, I doubt you'd get those numbers.

Numbers don’t line up. There are 30 million people in that age group in the US. 30% of that is nearly 10M. There may be fewer volunteers than that, of course, but that problem is fairly straightforward to fix: pay more, and get the hell out of the Middle East.
