That's funny.Germans with guns. It was a bad idea in 1870. It was a bad idea in 1914. It was a bad idea in 1939. it is a bad idea today.
Armed citizens are normally considered a defensive militia NOT offensive.
For offensive you need regular infantry trained troops.
The Germans will never go full out armed however.
They have been brainwashed by the Nazi's to tolerate disarmament and they have been disarmed ever since.
