Todays lesson requires that you remember what you were taught back in lesson 12 regarding doors.
As you recall. If you see hinges the door is a “pull door” and will open out. If you are approaching a “pull door” you need to be positioned on the doorknob side so that the door will not be opening in your face, becoming an obstacle to your entry. Which is “Bad JuJu”.
The one thing you don’t want in these situations is “Bad JuJu”.
Conversely, if you do not see the hinges, it is a “push door”. On these you want to position yourself on the opposite side of the knob.
This allows the point man to have an immediate and unobstructed path of entry and observation.
