Most definitely not.... probably more like 'some soldiers a signaler'.
26. All Arms soldiers trained to preform tactical signals functions. Signals MOS updated to enable all arms attendance on signals MOS courses.
My take on that is they will select suitable all arms soldiers and train them up accordingly. Especially these days, that's not a role you'd send someone to perform who wasn't up to the required standard in a bunch of skills and knowledge requirements not found in lot of troops.
