Did professionalization increase Civil War casualties?

Did rising casualty rates show that Civil War armies became more professional as the war continued?

Often, yes, but the types of casualties also matter.

The viewer links the changing casualty record to armies becoming more professional as the war continued. Casualty rates often rise as troops become more professional, but the types of casualties also affect the comparison. Raw totals alone cannot explain how military effectiveness changed. Casualties are therefore one qualified indicator of professional development.
