Alright, I forgot about this.
I have a whole bunch of stories from the time my dad was in the army, for a reunion they made a little book with all sorts of stories from their time as hussars. I'll try to make a nice story from a bunch of them.
Over there in the Netherlands we don't have those massive training areas like they have in the US or Germany, we have to make do with smaller ranges or have areas where we can't fire weapons. The only area where tanks can fire their guns is on a range called "Vliehors", which is on one of our islands. Every once in a while they go there for training, and of course, there has to be a first time for everything. Now, back in those days (1966-67) we had conscription, and conscripts were just assigned a role and had to make do. This did not always turn out well.
So, the newly conscripted tankers arrive at the Vliehors for their first life fire shots. They line their Centurions up at the firing range, the commanders give their orders and the Cents point their barrels straight at and old tank used as a target.
When the signal is given, all tanks fire, including the one aiming up. And of course he immediately gets the nicely asked question of "WHAT IN THE FUCK ARE YOU DOING YOU FUCKING MORONS!?".
Turns out the gunner heard "Target, brisance, 1800 meters" instead of "Target, armour, 1800 meters", so he aimed like he had an HE shell loaded (and seeing how it's written, he aimed poorly too). So basically he fired an AP shell at angles only used for long range artillery support. They never really figured out where that AP shell went. Probably somewhere in the sea.
And that's why we don't have more firing ranges! And it's also why that gunner immediately was a loader after that.
Anyway, during a later training...
My dad, as a fresh Hussar got the task of cleaning the gun of another Centurion. Of course, you can't have a live firing session with a dirty gun, now can you?
He 'happily' went on cleaning the gun, replacing oils, whatever you need to do to clean a tank gun. When he was done the tank was sent on his merry way to the firing range.
Seconds after firing a voice thundered over the range "HUSSAR BRONEEEEEEEEEEEEEEEEEEEEEEEEEEZ!!". To which my dad replied "Sir, I'll immediately get the end-caps of the recoil cylinders and get to cleaning, sir!".
I guess you can imagine how the inside of a tank looks when you forget to put the caps back on the recoil system of a tank gun, and fire it.
