Nothing confuses students more than INCONSISTENCY during training.
Clearing malfunctions isn't rocket science. Most malfunction drills are fairly similar in their schools of thought.
Example-> If you get a "double-feed" on your M4:
Lock the bolt to the rear. Drop the magazine. Rack the charging handle 3 times.
Insert fresh mag. Release the bolt. Good to go!
Stop the madness! Keep It Simple Stupid.
