Respect - people want to be respected members of their community.
tell me facts about it
Show people the benefits of joining the army. They are protecting their country and could make a difference
Talk about the wonderful benefits or the fact that you get a hefty bonus, Mine was 86,000 dollars. A steady job and paycheck during a economic crisis. If you work in the military they will pay for school, they can get you further into a career if you choose your MOS (job) right. Try that. That usually works and for the fact....generally people don't need convincing. They will already know if they want to or not.
