I worded that poorly, sorry. Businesses will contact the troops chain of command.

The military exercises a lot influence over troops, they can bust you down or remove your security clearance. They can also push you into payment plans and reflect these situations in your performance reviews. The military, for all intents and purposes, acts as much more than just a simple employer and lending services (among other businesses and people) exploit that.

The military provides your clothes, your housing, your food, your laundry, your transport, your healthcare, and your chaplain. They can control your schedule 24 hours a day, decide who you're allowed to call or write to and what you're allowed to say, and decide what electric appliances you're allowed in your quarters. They can change your place of work to a foreign country, prevent you from resigning, and even literally have you imprisoned or executed.

While in some regards the military is like an employer, in other regards it's very different.
