Short answer: Firehouse Subs does not run a standing year-round military discount, but it honors service members every Veterans Day (November 11) with a buy-one-get-one-free sub for veterans and active-duty military who show valid ID in store.
Who qualifies
The Veterans Day offer is for veterans and active-duty military personnel who can present a valid military ID or proof of service. There is no published year-round program for military families or first responders, so outside of Veterans Day, plan as a regular customer.
What you get
On November 11, buy any size sub and get a second sub free. The catch: it is in-store only (not online or in the app), generally limited to one transaction per customer, and it runs only on Veterans Day. Participation can vary by location, since most Firehouse Subs restaurants are franchise-owned, so confirm with your local store before you go.
How to claim it
No code, app, or third-party verification (like ID.me, SheerID, or GovX) is needed. Just walk into a participating location on November 11, order your sub, and show your valid military ID or proof of service at checkout to get the second one free. If you want to confirm participation or any other day’s offer, call your local restaurant directly.
