Active duty and vets with ID can get in anytime without tickets. Not sure about law enforcement, but check the site or call.
When I went, I was not able to get tickets. At the door, I had me 101st Airborne hat. I was told to come around the line and asked for my DOD government retiree ID card. My son has his dependents card. Thanked me for my military service and let me in.
I know military can get in so probably, but I'd check their website to be certain.
I'm not sure, the best I can offer is try it, they can either say yes or no!
