my information is about a decade out of date (i looked into joining the ffl a long time ago), but pretty much everybody told me it was an exceptionally retarded choice to join the ffl if you had the option of joining the us military. you'll be treated far worse (especially as an american), and the ffl is 10x more mutted-up nowadays than the us military is. just do what every other former marine does and join the army.
