Private Emma Elder, London Regiment, is a trainee paramedic in her day job:
"There's lots of really good links - the training's linked really well and I think a lot of paramedics are reservists in their spare time and then vice versa.
"I've always wanted to go into a combat role in the long run, so doing this was a great opportunity."
The targets for the cadre were the rusted hulks of old tanks that litter the range.
It was a test of numerous skills, from targeting to teamwork, as well as being technically proficient with the mortar and ammunition.
Those hoping to qualify had help on hand from more experienced colleagues.
Lance Corporal Henry Lam, London Regiment, was impressed: "They're actually doing brilliantly - from seeing them from day one picking up the mortar kit and so on, and now they're laying on relatively swiftly.
