He had put enough smoke bombs around the building to hide WHO it was, if not where, but clearly he hadn't done well enough, because he heard someone trying to rally a patrol to come find whoever was on the building. Still, he would be long gone by the time they got here, but he had one last thing he wanted to try. His first attempt at an actual rocket, though it was more like a bottle rocket with a good deal of charge than an actual rocket. He was not even sure if it would fly straight, as there had been no way to test AND hide it, so he had opted to hide rather than test. The fuse would, at least, ensure it didn't go off next to him. He placed it, using the raised edge of the roof and a handful of rocks to ensure it stayed mostly pointed at the target, and then lit the fuse, before jumping to one side of the house.<br/><br/>Once down, he pulled out another set of smoke charges, and activated it, and then threw it, before making his way to the entrance of the Vault under smoke cover.
