in response to iron rations query swords take priority over rifles. both can be worn, rifles on stripes swords above. depends on how sad you are. when i was serving both had to be worn as described providing you were entitled to both. hope this helps. if still in doubt ask you regt tailor or qm/rqms in clothing store.
I was always led to belive that it goes on course seniority! If you are skill at guns trained they go above your rank and then your cross swords go on your lower right forearm!! But I dont really give a shite... why wear them thats what I say! Im PTI trained and I dont bother..
From what I recall, and I stand to be corrected, the AIPT qual is very much a Junior rank qual (it was when I did it). By the time you reached Senior rank, you were expected to have attained at least your class 2 in preparation for APTC Probation (which I believe is now all one course?) or jacked in the PT instruction bit altogether. After all, if you're a SNCO class 3 PTI, doing the same job that a Lance jack could do, how is that reflected in your CR? "Sgt bloggs performs JNCO duties to an above average standard." Great.
