Footage-style CQB
Your view is low and tight. Pre-aim head height at every jamb, not the floor.
Room order sits in this resource.
Door checks
Slice the pie. Do not shoulder-swap into a packed room without a flash or a teammate.
Closed doors can still have a gun on the other side. Listen first.
Squad comms
Short calls beat stories. Additional game information keeps contact reports useful.
If you die, say the angle, not the essay.
