Allow me to provide a synopsis of the documents:
The first document ("Führungszeugnis") is a certificate of conduct. Mr. Kächelin had served as a Kanonier (lit. "gunner", i.e. an artillery private) with the 11th, later the 5th Battery of Field Artillery Regiment "King Karl" (1st Wurttembergian) No. 13 from 14 Oct. 1898 through 28 Sept. 1900. His conduct was good; he was not subjected to any judicial or administrative punishments.
The red document ("Kriegs-Beorderung") is a notice for the event of a general mobilization. In the event of mobilization, Mr. Kächelin was to report to the Boys' Elementary School at Göppingen by 10 A.M. on the 4th day of mobilization without awaiting additional call-up orders.
The data in his military passport ("Militär-Paß") is as follows:
