CPLs who can be promoted to 3SG because of vocation, may be
promoted to CFC instead if they are not sent for section leader
course, e.g new batch of tech specs.
IMHO, it's stupid. The fella who crafted this policy didn't take
into account that tech specs play an important role in a battalion
orbat, and they require their 3SG rank to carry out certain duties
without being hindered.
I don't believe a CFC can sign for a weapon fit-for-firing cert.
