It's less likely there will be a separate code of law and justice system. The service might have to obey the civil law code, both personally for the troops and collectively abiding by stuff like workplace safety, and civil rights.

Orders are probably at least a little more open to discussion - civil law isn't likely to allow anything more serious than firing you for disobeying one, or publically questioning your superiors stupidity, executing you isn't an option.

The pay scale may not be as flat as it is now. Flag officers might draw the kinds of multi-million dollar salaries corporate executives do.
