For those unfamiliar with it the patrols badge (it's not called patrols now) looks like a small trig point map symbol.
I did wonder what the 'patrols course' was - AKA 4/73 (Sphinx) Special OP Battery. Although a RA unit, they'll take anyone who can pass selection and I dare say it probably turns out some very good soldiers back in to Bns.
You could probably also include Pathfinders in amongst the list. Reputed to be a step above 'normal' Para and often seen as a stepping stone to SF. My first encounter with PF was HERRICK in 2006 when they went into MSQ to shore things up. As I recall, they were only supposed to go in for a few days but I think they were finally extracted about 6 weeks later. They really weren't happy campers by that stage, and frankly, who could blame them!
