Rommel would hang as a war criminal after the war, no one left the eastern front German army without some pretty severe stains on their record.
Rommel's Chief of Staff Hans Speidel was made NATO ground force commander in Europe in the 1950s was a general in the East beforehand. Marshals in the East that gave out war criminal orders at best got slaps on the wrist like Manstein who served four years in jail or Von Rundstedt that served no time in jail.
Model if he didn't blow out his brains likely would have gotten a Manstein length sentence. The generals who swung tended to be the desk generals that gave out criminal orders, but never risked their necks themselves.
