Where might I get stationed as a Crypo Linguist who is hoping for Russian as a language?

Since you're Airborne, there's a good chance you will be stationed at an SF group. When you go to DLI, before you get placed on your phase 2 training follow on orders, contact your branch manager for an assignment. Schools that are PCS length, the new branch manager directs the assignment. Schools that are TDY length, Retention branch does the assignment.

Listening post in Alaska, Canada, Iceland, Turkey, and Europe are possible choices.
