Modern Day Marine is the Marine Corps’ premier annual exposition and symposium, offering a dynamic platform for fostering collaboration and innovation, both internally across commands, and externally with Congress, industry, and other critical mission partners. This year’s show is expected to draw approximately 9,000 attendees.

As a member of Congress or a congressional staffer, Modern Day Marine lets you gain firsthand knowledge of Marine Corps priorities while connecting directly with more than 400 exhibitors, including companies from your home district. This event showcases how these businesses contribute to our national security and your local economy. It provides a unique chance to engage with industry leaders, understand the challenges facing your constituents, and strengthen ties with the businesses driving innovation and creating jobs in your district. At the Congressional Breakfast, you’ll have the chance to hear directly from the Commandant of the Marine Corps and engage in a Q&A panel with senior Marine leadership.

Both Modern Day Marine and the Congressional Breakfast are free for you to attend. We encourage you to take advantage of this invaluable opportunity to support and advocate for the business and people you represent.

For Communication Directors and Press Secretaries:
Modern Day Marine provides the Marine Corps with our most influential messaging engagement in the annual calendar. No other single engagement produces more news coverage for the Marine Corps. Our 2025 show generated more than 320 news articles which reached an estimated 260 million people globally, a 24% increase over 2024’s show. Approximately 40 defense and national reporters will attend this year’s show, representing several dozen newsrooms. This presents a valuable in-person networking opportunity between offices and committees with defense ties and the journalists who cover this space
