What used to happen with Interpreters is that they would join the Army, first thing get a $100,000 language education at the Presidio of Monterey, and then claim homosexuality so as to get booted. They then would go sell their services on the job market. This slowed down a lot when the Army caught on, now most people need to be in the Army a few years before they get the free education.
My wife is a 1sg, so I know that especially women, use homosexuality as a get out of the Army free card card when they decide they don't want to do it anymore. Given how stressed the force is the Army is interested is closing the gate, but the problem is that this is a huge change, and the Army can't do it right now.
