Aha, it was Kylo! And this also handily explains why the planet wasn't blown up; it's hard to find something like a map when the planet it's on has been blown to smithereens. These troopers and PIE fighters really made quick work of the bar. They're also interestingly still flying around in the sky by the looks of it; there's not much left for them to do I suppose except look menacing, do a worse job of looking for survivors... prevent other ships from taking off. Hm. Well, I bet we'll be seeing another Falcon-PIE chase scene soon then!

Also interesting is that Rey isn't mentioned as one of the objectives. And that it's Han Solo, not Yanni or some other name. I bet this sergeant doesn't last that long for making these assumptions. Evil empire minions aren't usually selected for their initiative, and accidentally acting contrary to the leader's goals is a good way to quickly buy the farm. No guarantee that any of their objectives are still under this rubble pile either; a decent bar would have at least a back door to slip out of when things get too hot.
