Create projects that would help people interested in joining the Marine Corps.
I would suggest things like:
-history of the Corps
-physical fitness tips
-how to get a good recruiter
-things that would be helpful to learn before shipping out to Boot Camp
-how to become an Officer, during or after college
-fun facts about the Corps
If you would like to curate, please leave a comment and I will get back to you as soon as I can.
