Pretty good juxtaposition. But if you fail the assessment, then you can't do it.
Irrelevant. Failing a safety test has no bearing on how good at shot they will be, you're right, but if they can't pass the test they can't shoot. So a pretty moot point.
Some nonsense... I failed my first test, some 'nonsense' too. But I learnt from the mistake I made. If a cadet fails on some 'nonsense' during the WHT, they need to learn from where they failed. The test isn't some nonsense, it's a safety procedure to allow them to safely handle the weapons system. Regardless if you think it's nonsense, the MOD who use the exact same test (minus the change lever) for their full time servicemen don't think so.
