Is there a Military Discount for ATT Internet & Direct TV?

We currently have ATT Internet & Direct TV. Recently we had someone come to our door trying to sell us an ATT Package. We told them we already had ATT & Direct TV, they asked us if we were getting the Military Discount, we said no. They told us to contact ATT & see about getting our Military Discount. What do I need to do to get this discount?

Thanks
