3 disc objects flying together and then just took.

I was heading to work and my little girl said birds and pointed up in the sky. I saw some black birds but higher above them was three objects. The middle one got close to the first one. And at that point they started going up fast. We saw them about a min or two because I was driving. A tree got in the way and I got clear of the tree and the objects were gone. The day was clear and the sun made it reflect. It wasn't a plane or a jet because I was in the marine corp and refueled aircraft and know what I saw wasn't from here. My wife was with me and just took a glance at first tell I told her to look real good. She was like what is it? I just said I don't know. They weren't too high in the sky.
