It's useful (if it doesn't die) for scouting. From above, it will have a better look at the terrain, helping mission control do path planning and terrain/risk assessment. I have no information telling me that's going to happen, but this is my fairly educated guess as to how the drone could be used.
Ok, that could be a use for it. They do have satellite images, but I guess those are much lower resolution and a better satellite would probably be orders of magnitude more expensive.
