Didn't the Romans show us to not man their military with foreigners, people with no allegiance to the country.

Why yes, they did. But don't let the facts of history get in the way of an agenda

Military to allow undocumented immigrants to serve

A small number of undocumented immigrants in the U.S. will have an opportunity to join the military for the first time in decades under a new Department of Defense policy unveiled Thursday.

The new rules will expand an existing program allowing recruiters to target foreign nationals with high-demand skills, mostly rare foreign language expertise or specialized health care training.

For the first time, the program — known as Military Accessions in the National Interest, or MAVNI — will be open to immigrants without a proper visa if they came to the U.S. with their parents before age 16. More specifically, they must be approved under a 2012 Obama administration policy known as Deferred Action for Child Arrivals, or DACA...

...The Pentagon program is capped at 1,500 recruits per year. Officials say it's unclear how many of those might be unlawful DACA status immigrants as opposed to others who are also eligible for military service under MAVNI, including those with legal, nonpermanent visas such as students or tourists.

Estimates suggest between 1.2 million and 2.1 million children, teenagers and young adults in the U.S. have no legal immigration status but meet the criteria for the DACA program. Those targeted by recruiters under the MAVNI program likely will be immigrants with language skills critical to national security, such as Arabic, Chinese, Pashto or Persian.

But Pentagon officials don't know how many of those immigrants have actually learned their ancestral language to the proficiency required by the military.

"We're just not sure how many within that existing population of DACA would have the linguistic skills to qualify," said one defense official familiar with the policy change. "These are kids who entered the country at a fairly young age and have basically grown up in the United States, so the limit of their language talents would probably be the language that they received at home."

Don't argue there is a major issue with language skills. While I was overseas in Kuwait ten years ago we had a warehouse of Iraqi documents waiting translation. This was a painfully slow process and it highlighted the lack of translators we have. But it's not we didn't know that. War story, back in 1991 I was a platoon leader in the 104th Military Intelligence Battalion, Fort Carson CO. This was the end of the Cold War and I had a platoon of German and Russian linguists. As we no longer needed them, we gave these soldiers who had gone through 8-12 months language training a bonus to leave. We're talking 30-40K. And AT&T said "Come on in, we need linguists, here is 50K a year!" So here we go again.

Now here is another issue.

DACA status is granted by the Department of Homeland Security and includes a background check.

I handled security clearances for most of my career and one major issue is family. We need to know if the candidate's brother or step-sister is a known radical. Or half the family is in prison for felonies. The acorn don't fall far from the tree and this might bring the judgement of soldier into question when handing Top Secret codeword material. Or we may not be able to get to their families and check them out. My senior year in Tulane ROTC we had an excellent cadet who was originally branched Military Intelligence. She was also half Vietnamese. We could not check her family out and that ended her time in MI (She was rebranched into the Quartermaster Corps). This was one issue. Imagine ten-thousand of them.

As Princess Leia said, "I have a bad feeling about this."
