text: what is the best branch of service if i want to specialize in languages or international affairs as an officer i hate the army. any other branch besides the army. and if you know specific job titles in these branches please let me know. all of the services have about the same positions in languages or int. affairs. translator, or embassy duties would be jobs. i think the best service is the marine corps. nothing like the pride of being part of the elite fighting force. former marine.
