Wandering off into personal anecdotes again...
When I was doing that live fire shoot, a mob of roos decided to wander into the range area. When the first gun started firing, they scattered but given that our arc of fire was over their heads to hit a target zone behind them, I doubt we hit any of them - but it must'a scared the roo-poo outta them!
However, if they'd been an hour or so earlier, they would've been fragged by the mortars (by the time the roos showed up, mortars had switched to Illum for us on the SFMG course).
Could'a been a nice little barbie, what's a few bits of shrapnel here and there when your getting fresh meat instead of ratpacks hehehe
