We hunted around online, and came to the conclusion that it is in the russian server, but not ours. This is a group of 4, hunting 30-60 minutes for it, and even checking the spot where a picture shows it to be (The black bar under the computer isn't in there for 2238, but was in the picture. Concluded that its simply not in 2238 or something
So unless its been added in the last week, i don't think the sierra army depot has one. You can still try to route power to it, seemingly allows you to, but still no terminal.
