Presumably your Grandad was in the RAF Regiment, because he is doing tasks which are more infantry based. The RAF Regiment provide the RAF with airfield security, amongst other ground-defence support.
Performs duties as a member of a rifle section
. This means he was trained to be part of a small team of RAF Regiment Gunners (as they are known), armed with rifles, to provide security to an RAF Station (could be entry security, or patrols around the perimeter of an airfield)
Carries out personal decontamination and decontamination of small arms
. Decontamination (cleaning) refers to the RAF Regiment's responsibility for providing specialist support for nuclear, chemical and biological warfare. So he was trained to decontaminate himself and his rifle (which is what a small arm is, rifle, pistol type weapon). That doesn't mean he was ever actually involved in real NBC warfare, everyone was/is trained.
Assists with the handling of casualties, and administers first aid
. This is another war task that the RAF Regiment were and still are trained in.
May be required to perform duties as a member of a 3 inch mortar detachment
. Mortars are the type of 'bomb' you see in war films, a small tube on the ground, which the soldier drops the shell down and it blasts straight out. The RAF Regiment would use them for airfield defence, to stop airfield attacks from ground troops. Not sure how many in a mortar team, but 3-4 I think.
and under the supervision of an armament fitter to undertake minor servicing of small arms and to assist in servicing LAA equipment.
This means that under the supervision of a trained weapons technician (an armourer) your Grandad was trained to undertake basic fixing of rifles. I think LAA Equipment is Light Anti-Aircraft Equipment, this was certainly used by the RAF Regt in the Far East, not sure if that means your Grandad served out there, or if we used it in the UK.
When required commands a rifle section or acts a 2 inch mortar man
, So he was trained to lead a rifle section. I think it might mean acts as
2 inch mortar man, which is simply a size of mortar (small)
when qualified may be called upon to act as deputy commander of a 3 inch mortar detachment.
And as it says really, when trained he could be deputy commander of a larger, 3 inch mortar team.
This profile suggests at the time it was written your Grandfather was a senior Gunner or perhaps a Corporal.
