Collection of Int is done by many level of operator both in the Intelligence trade and out.
HUMINT courses are run for anyone who is suitable, you do not have to be int to get them.
As an Int Op (NCM) I collected SIGINT... but that was just my tasking. Others did map work, some did analysis...
I am not sure my IntO did any collection, I never saw him do any any, but that doesn't mean that he didn't. He did mostly colaltion, analysis and dissemination.... perhaps Journeyman can fill in on the Int O role (*snicker*)
You mentioned RMS Clerk, so I am not sure if you are looking at NCM trades as well, and am by no means an expert on the vision requirements for them, but you may want to check out Sig Op and Comm Research too - they may be of interest to you, if you qualify.
