When I was in the Army and stationed in Germany during the Cold War, we trained differently that the Air Force.
I was a Fire Support Specialist (Forward Observer) we called Artillery, Naval Gun Fire and Close Air Support (from Air Force).
Out in the field we work in tracked vehicles, sleep in leaky tents and eat one "hot" meal a day that was trucked out to us.
We worked 12 hour on and 12 hours off.
Some times the Air Force would send out an Air Liaison Officer to work with us. They'd show up in a rental car that they drove from the Gästehaus (motel) they were staying in. They work 6 hours and then drive back. Eat in a restaurant and sleep in a bed.
