Yes the Stars and Stripes games will be with the college Stars and Stripes Academy attendees. My understanding is that the games are regular season RMFL games instead of a post season tournament like last year. I think it's a great idea.
Rules are posted on the rules tab of the website. AA will remain high school rules with adaptations and AAA voted on college rules with adaptations. The only change affecting both leagues is that owners voted on making mouthpieces and shoulder pads mandatory.
