passing rate is 95% first time after 2 weeks of intensive course, 2nd time almost 100% pass, unless you failed yourself on purpose.
the most challenging will be reversing the 3 ton in pararell parking without guidance.
But in real reservist unit, you will not drive 3 ton but 5 ton which is auto, there will be no pararell parking and it's a must to have ground guides to park, so relatively safe.
You can choose to drive land rover/ OUV if your units have vacancies.
One lucky guy will be the GP / admin car driver if there is vacancy too.
I prefer to drive land rover,but manual vehicle.
OUV is fun to drive, a powerful vehicle which cannot exceed 50km/h, just step a bit and the beep will start.
