No, I do not think he would continue military service. It is not clear from the wedding record that he married in a "regular" vacation, or whether he was prematurely released before serving for three years (eg because he had to take care of the farm).
The compulsory military service and the resulting military service were considered "necessary evil" in Bohemia. Whoever could have avoided it.
A passport and perhaps a permit from the county office [?] was needed to emigrate abroad. One condition, however, was certainly the completion of military service.
A bit of luck kept record of his military service. Unfortunately, the Military Central Archive website is only in Czech and personal documents are not digitized. Documents for the birth years 1750-1864 have survived torsionally. That's why I'm writing with some luck.
