actually, in my active unit a long time ago, the 2 clerks were the
scariest bastards around...
one was a SAFSA rugby forward, the other was built like a tank
because he did bodybuilding..
both of them were PES C coz last time, being flat-footed
rendered you PES C and they became clerks 
but they were not trained to repair armoured vehicles, put out
fires, do heli-ops etc right
