Here are some more Star Wars: Episode VII photos from Greenham. The characters are near X-wings and the Falcon and they look like rebels. Some of the extras costumes remind me of background characters from the series Star Wars Rebels to be honest. They have just have that look to them. If you watched the video last night from the drone, I think this transport is what we saw driving on the ground that appeared to be a car, perhaps.
Thank you Rick Lawrence for sharing your photos!
