you dude dependes on what range your are looking at runing, a rmq can run run most ranges as a rco how ever a skill at arms inst would be the better qual to have.
if you need any more info then get back to me
Stage 1, indoor range,grouping and zeroing, Stage 3,Etr ,falling plates,Stage5,Field Firing ,fire and movement exercises plus disposal of Dud ammo, on the ranges these were the qualifications taught by the SASC 25 years ago ,its probably changed by now.
The RMQ qual has never qualified personnel to conduct wht!!! the RMQ course used to cover stages 1 -3 and having passed the course the individual is awarded the SA (B) 90 qualification to allow the receipient to plan conduct and supervise LFMT.
They do both award the SA (B) 90 but the skill at arms course also awards SA (E) 90, SA (H) 90 and SA (M) 07. As well as qualifiying the individual to conduct WHT provided that he is current and competent on that weapon sytem. RMQ awards the SA (B) 90 and that is it.
