Why was he here again? Oh right, the Supreme Commander wanted everyone to be here for the unveiling of the AT-HO. He heard rumors of it but had actually seen it, apparently they used the old AT-AT he and Commander Milo found underground to make to the frame of the walker. He was excited but he was also terrified of what it could do. If the stories were true about the AT-HO it would be able to destroy almost all opposition that the First Order had.
