T-37 and T-38 weapons

What practice weapons do these two planes carry. I know the T-37C has two underwing hardpoints. The T-38C has some as well. Do they just carry 25 lb. practice bombs? I have heard of gun pods on the T-2C Buckeye. Can the Tweet and Talon carry these too. If so, what kind of gun pods are they (designation, caliber, # of rounds, etc.)? Any info would be appreciated. These two planes fly over my house every few days for touch and go practice at our airport. It is a lot of fun to watch them. I saw a two T-38’s this day, and they had separate paint schemes. I wonder what was up with that?
