I liked the layout, good work with that.

But:
Please remove all the civilians from the map. They are the most useless thing in the game that wreaks havoc and cause unnecessary chaos. You tell them to leave but because there is no civilian exit on the map or nearby, they decide to run around and open door(s) which you were maybe wanted to take or maybe hold on to and not take. In the real world, they arrest everyone because people are unpredictable when they panic..

Having civilians in "training" maps is a real bummer. In my case, it makes me want to alt+f4 because there are civies in any map.

I am on board with having lots more enemies but not with having even a single civilian. Make them hostages. HR puts a little pressure to the team that we need to be quick in getting them out. Though in game(s), unless you are running on time, HR has no difference than Bring Order to Chaos / Kill Everyone.

My Delta Force buddy team clean blind run: https://youtu.be/Ia5h8SRQNYQ
No wall breaches, no frags, bangers only where needed. As per my personal SOP with this buddy team, I go explosive on most doors that have no room to stack up on the handle side.

No XB is "No explosive breaching"

I had fun in the first succesfull run, though i'd like to know what "no XB means
