How do mortar platoon leadership conduct the FDC examination?

KSAs then coming up with ELOs and TLOs then working with instructors formulating questions and answers….there is a specific computer program that walks you through all of this, once that is completed it must get ran through HQMC and or chain of command for approval.

Isn't how you grade depend on if they can't do the crew drills to achieve rounds per minute using safe actions, if they fail 80% on the written and cannot work as a team?
Ask yourself - what are the standards required surely since you have done his before creating it from scratch again isn't a problem.
I found if I asked the complainers to give me a written report, none ever came back with you. The response was usually crickets.
If they asked me why they should do a 'written', I would respond with, "If you don't care enough to give me a written critique then I see no reason to pay attention .
A word of advice - it doesn't matter if things go wrong or right (because nothing ever over all the way good or bad) - someone will arrive after the fact and complain about how you're doing it. So you might as well go ahead and do it your way., because you really are dammed if you do and dammed if you don't.
