I am more referring to the U.S. Army intranet system. Which while some services can be accessed from the internet, some can only be accessed while connected to the Army Intranet. The Amry uses alot of terminals, computers, that have no need to connect to the internet but only the Army intranet.

Also, the Army modfies some of the programs and hardwere they use, such as Windows from their standard commercial versions, removing or changing features and such.
