Reinz:
I volunteer to be one of the assistant instructors for your course -- provided that I can use the teaching techniques employed by R. Lee Ermey as "Gunnery Sergeant Hartman" in
FULL METAL JACKET. As such, before introducing you to the students, I could conduct preliminary proceedings somewhat along these lines:
[size=10]Assistant Instructor: A-ten-hut!
[Students come to attention.]
Assistant Instructor: Present Arms!
[Students unholster their R9s and hold them at the ready, muzzles pointed up, trigger fingers alongside the frame.]
Assistant Instructor: Pray!
Students: [chanting] This is my R9. There are many others like it, but this one is mine. My R9 is my best friend. It is my life. I must master it as I must master my life. Without me, my R9 is useless. Without my R9, I am useless. I must fire my R9 true. Amen.
Assistant Instructor: Order, hut!
[Students reholster their R9s.]
Assistant Instructor: Parade rest!
[Students adopt the parade-rest position awaiting your entrance.][/size]

Seriously, though, that is excellent advice and a very generous offer on your part.
