The course that BB17 brought up is the specific course I was inquiring about. I was specifically wondering whether or PLQ was necessary, as the crse sounded like something that would build on the ARSO skills taught there. For those that are interested, the most recent pre-requisites are being qualified Pte(T) (although apparently Bde will load pers who are qualified only SQ or DP1.1 Inf), be able to pass a handling test for the C7 and C9 (not 9mm as was mentioned earlier) and a reccomendation from the CO.
The course itself teaches coaching the grouping practice (5rd and 20rd), coaching elementary and advanced applications, some of the physics behind a bullet's trajectory, mathematical equations to determine whether or not a sight is properly zeroed, how to zero the C79A2, coaching the C9 LMG, how to use the CFOSP, techniques for dry zeroing, proper firing posns (taught by a Queen's Medalist this year), among other topics. It's 5 trg days, 2 in the classroom, .5 for testing, and 2.5 on the range. It's run and staffed exclusively by 1NSH pers, and held at CFB Aldershot. Students this year were also able to get some hands on time in the SAT before heading out to the range. Excellent and extremely informative crse, I'd encourage anyone that gets an opportunity to take it.
