Which sequence describes how to clear a class 4 malfunction?

The sequence "Tap, roll, rack, assess, press" effectively outlines the steps to clear a class 4 malfunction in firearms handling.

In this context, "Tap" refers to firmly tapping the base of the magazine to ensure it is properly seated in the firearm. The "roll" action involves rotating the firearm to the side, which allows any stuck casing to clear the chamber. "Rack" means to pull the slide back, which will eject any misfed or jammed cartridge. After racking, "assess" is critical to verify the status of the firearm and ensure it is ready for use. Finally, "press" involves preparing to fire once all checks have been made and the firearm is deemed operational.

The other sequences do not specifically address the steps necessary to address a class 4 malfunction in the most effective order. They may involve aspects of firearm handling or malfunction clearing but do not correlate as clearly with the recognized procedure for a class 4 malfunction like the correct sequence does.
