yes

When you join Inf you get told to watch out for drop bears, hoop snakes and cassowary's..so I thought they were BS and used to laugh at the guys saying "dude..seriously..be carefull of them, they fuck diggers up because when you're on night sentry you hear two feet stepping thru the bush, you challenge, no answer so you arc them up and freak them out and they charge and tear strips off ya" ..to which I'd respond "yeah whatever dickhead..I'm not stupid enough to believe that shit!"
Anyway...
I was on an exercise in Tully and standing guard in this shitty guard box doing base protection. It was hot and boring and I seen a white plastic bag sitting in the middle of the track 50mtrs away and thought "wtf is a bag doing out here?" fuck it, i'll go get it.
(keep in mind Jurassic park had just been released and Id seen it)
I was bending down to pick it up when (to me) a velociraptor came screaming out of the bush to my right and did the claw kick thing at me..I FUCKING SCREAMED AND RAN.
As I was running back to the guard box I could hear it at my feet grunting and chasing me.
I ducked into the guard box and slammed the door..this thing smashed it horn straight thru the cardboard like door and started savaging it with its claws and just fucking screaming at me....I was screaming back..like a terrified girl.
The box had a little window on the side so I took my rifle off safety and stuck it outthe window and emptied a clip at it...only had blanks in it due to it being an exercise and whilst they can hurt or even kill a man..it just pissed this velociraptor off like you wouldn't believe.
The radio went off as my Sgt wondered what the gunfire was about so I jumped on the radio and screamed into the radio "A VELOCIRAPTOR IS ATTACKING ME..A VELOCIRAPTOR IS ATTACKING ME!!"
What seemed like hours later the sgt has rocked up in a jeep and seen this thing just going apeshit at the door he beeped the horn and nudged it with the jeep..it ran around the back of the jeep and launched at the door again (I meanwhile was pushing on the door to keep it shut as this thing was busting it down and its claws were coming thru)
In the end he had to hit it fucking hard and it pissed off, he opened the door and I was a fucking mess.
he says to me "what did you do to piss the cassowary off?"
I said "Cassowary?..theyre real? I thought they were bullshit..are drop bears and hoop snakes reall too?" (in the most terrified/girly and frightened voice imaginable)
We theorize it was so angry because we must have been near its nest, the bag must have puffed up with the wind and it thought I had an egg

Was a bad day....let the laughter begin
