I think there are two key ones you should look for:
1/ Tickets. This is likely the best. They should be available at your base or you can get right at Disney. These tickets are 3-4 day hoppers and are deeply discounted.
2/ Hotels. You need to call for this but Disney properties are 40% for military. The catch is that they have limited availability so call early! Free to cancel so you may as well hold it.
Enjoy!
